The central interior light of the VAZ 2114 is flashing (resolved)

There are a lot of videos of the same type on YouTube on how to make footwell lights with your own hands, where the wires lead from the door limit switches or the ceiling lamp, but my laziness found a new and quick way to make footwell lights on a VAZ-2114. I may not be the discoverer of this method, but I have never seen anything like it anywhere. So, let's look at the contacts of BI BSK.

Contacts BI BSK VAZ 2114

In my car, the footwell lighting is implemented through an open door indicator, the signal of which comes to the BI BSK, so this method can be considered the fastest and simplest. Operating principle: when the driver's door is opened, the signal comes to pin 6, and when the other doors are opened, the signal comes to pin 7. If you look at the signal table (below), pins 6 and 7 are ground. To make the backlight quickly, you will have to “work around” the car electrician a little. We power the positive wire of our backlight from wherever it is convenient, even from the cigarette lighter, and connect the ground wire to pins 6 and 7 of the BI BSK chip. Everything is ready, all that remains is to power the LED strip to the connected wires. In the end, we spent about half a meter of wiring and saved a lot of time.

It is worth noting that in order for the footlights to work correctly, you will have to connect pins 6 and 7 to each other, this did not affect the operation of my car in any way, at least I personally did not notice any changes. You can also theoretically consider other conditions under which the foot lighting will work; if interested, read after the signal table.

Replacing the backlight

In analysis
To improve the quality of your dashboard lighting, it is advisable to install new LEDs in place of the old ones. They provide excellent illumination, consume minimal energy, and guarantee a high level of data reading.

Buy a set of LED lamps, having previously calculated the number of devices needed for each sensor.
After removing the block, install the resistors and lamps in specially designated places on the VAZ 2114 - in the sockets. To dismantle the cartridges, they are carefully unscrewed counterclockwise. New sockets are installed in their place and light bulbs are inserted. Respect the polarity and position the LED heads. They will have to be carefully ground off.
Connect the power and check how the new backlight works.
Reassemble step by step. Be sure to route the wiring to the board and carefully secure it to it. This way, the backlight components will not interfere with the reassembly process.
Make sure the instrument panel arrows are positioned correctly. When trying to quickly complete a job, they often become deformed and bent.
The backlight structure is fixed with screws.
The power for the LEDs is connected to the power supply for the light bulbs, the arrows are put on and set to zero.
Using the on-board computer, check the operation of each sensor and device. If the IDs are functioning correctly, return the instrument panel to its original condition. That is, assemble the entire assembly.

Why the light in the cabin does not light (main reasons)

Car interior lighting is part of the electrical system, and therefore, in any case, it is worth looking for the problem in this part of the car. Of course, it is recommended to study, at least superficially, technical electrical diagrams in order to be at least a little up to date.

So, what do you need? A detailed diagram of the car's electrical components, a little ingenuity and a minimal set of tools. Let's look at places where the problem may be hiding:

Bulb.
Ceiling lamp.
Fuse.
Wiring.

We fix the lights and get acquainted with electrics

Since the main fault locations have been identified, you can safely move directly to methods for solving the problem. It is worth noting that with automotive electrics, not everything is so simple, but since this is a VAZ-2114, everything can be said very clearly here. Let's move on to methods for solving the problem.

Bulb

The first thing you need to check is the lighting lamp, since its burnout can cause the light to go out in the car interior.

In order to get it out you will have to remove the lamp cover. After this, you need to check whether there is a filament, and insert the lamp into the control device or simply connect it to the battery. If the lamp lights up, then it is not the cause of the malfunction.

Ceiling lamp

More than once, the cause of the malfunction was the lamp itself, where the contact group simply melted and closed, which caused a burnout or a blown fuse.

To diagnose it, you will need to remove it from the car and visually inspect it. It is also recommended to ring the contacts going from the lamp to the wiring.

Fuse and relay for VAZ-2114

The next reason is a blown interior lighting fuse. This part can burn out due to a short circuit, which for various reasons occurs in the on-board circuit. Often the short circuit is caused by a malfunction of the lampshade.

Wiring

Electrical wiring is every car enthusiast's nightmare. For some, everything is clear, but for others, it’s a “dark forest.” So, during diagnostic operations, it is necessary to ring the wires going from the lampshade to the power supply or button.

The VAZ 2114 has two blocks

The electrical circuit of the VAZ 2114 fuses is divided into two mounting blocks:

The main set of instruments is mounted under the hood on the left side (when viewed from the driver's position). The plastic cover is held on by latches, with the help of which it can be easily snapped off and can then be removed. The inside of this cover is equipped with a layout diagram that shows the rated current for each element. A detailed electrical diagram of the mounting block with the order of connecting contacts to the plugs is shown in the Lada 2114 instruction manual.

It is not allowed to insert a fuse whose amperage exceeds the permissible values in the circuit. This puts electrical equipment at risk. There are tweezers in the upper right corner of the mounting block. The design of this unit provides seventeen working fuses (which are schematically named F1-F16) and four backup protective elements (F17-F20): gray (2 A), pink (4 A), yellow (20 A); green (30 A).

The second mounting block of the VAZ 2114 is located in the cabin under the glove compartment, to the right of the central instrument console. You can get to it by moving the passenger seat all the way back. This mounting block includes a protective element for the fuel pump (with a rated current of 15 A). The remaining ES are designed to protect the fan relay, speed sensor (built into the gearbox), and mass air flow sensor.

The rated amperage of the element is 7.5 A. An element with the same rated current is provided for the ignition unit and ECU.

Backlight doesn't work

In cases where the light in the interior of a VAZ 2114 does not turn on, drivers who do not understand the electrical equipment of the car and its repair immediately begin to go to the Internet and try to find some advice or a solution to the problem there. But, no matter how strange it may be, you can fix the interior lighting of a VAZ 2114 yourself, you only need a minimum of tools for this and a detailed action plan, which we will analyze today.

Initial check

It is better to start repairs by checking the functionality of a specific lamp - perhaps the light bulb has simply burned out and will simply need to be replaced. If the light in the interior of the VAZ 2114 does not go out or, on the contrary, does not turn on when the doors are opened, then you need to check the door switches for functionality, you need to see if the contacts are in order, if they have oxidized, then it is better to clean them and wipe them with alcohol.

There are also certain nuances if there are LEDs. Typically, drivers prefer to replace conventional lamps with LEDs as quickly as possible, this is due to the following factors:

Cost-effective;
Longer service life;
Light brightness is much higher at low cost.

But when operating such lamps, it is necessary that the electrical circuit be fully taken into account, since for LED lamps it is important that the polarity be observed. So you need to check the plus and minus and if so, then turn the light bulb the other way and see if it lights up after that

In any case, it is better to remake the lampshade of the individual lighting of the VAZ 2114 for LED lamps so that it produces more brightness

So you need to check the plus and minus, and if so, turn the light bulb the other way and see if it lights up after that. In any case, it is better to convert the lampshade of the individual lighting of the VAZ 2114 to LED lamps so that it produces more brightness.

Also, on all light bulbs you need to check the voltage at the contacts and find out whether current is flowing there. If it is not there, then you will have to look for a broken wire somewhere in the wiring. This will require disassembling certain parts of the car, but there is no getting around it - if the interior lighting of the VAZ 2114 no longer works, then it needs to be repaired

The greatest attention still needs to be paid to the limit switches; often the problem with breaking the circuit lies precisely in them; a wire can easily break there, and you won’t even notice it

The filament in the light bulb has burned out

The first thought that comes to mind if any light source does not turn on is that the light bulb has burned out. Car lamps are designed in such a way that the low beam filament can burn out while the high beam filament is working. That is, in halogen lamps there are two separate filaments, and the breakage of one of them has no effect on the performance of the second.

To replace a light bulb, it is not at all necessary to contact the services of an auto electrician. All you need to do is follow these steps:

open the car hood;
remove the protective cover on both sides of the headlight;
disable contact group;
remove the spring clips;
remove the burnt out light bulb;
insert new one;
Carry out all preparatory steps in reverse order.

At the same time, we should not forget to follow some rules:

It is recommended to wipe the surface of the flask with alcohol before installation, otherwise it may immediately burn due to the presence of greasy or dirty stains;
Do not touch the flask with unprotected hands, as this may lead to contamination of its surface. This is best done with cotton gloves, but you can also use a napkin or rag.

Solution

The stores offer several options for light sources for replacing lamps in the instrument cluster:

traditional incandescent lamps,
LED in a plastic socket,
SMD LED is a more expensive and reliable option, a super-bright diode.

The choice will always depend on financial capabilities and lighting preferences.
The number of backlight and control lamps is up to 19 pieces. It varies slightly depending on the design of the instrument cluster and the modification of the vehicle. Many car owners choose LEDs due to lower energy consumption and longer service life. This backlight is brighter and gives an interesting bluish color instead of the standard green. But due to the design of the diode, the brightness control of the instrument illumination will not work, always turning it on at full power. On a long road trip at night, this can be distracting and irritating to the eyes. But in any case, the choice of light sources is yours.

Required spare parts

Before you fix your dashboard, you need to decide which bulbs you will use to replace the ones that have failed. You can use the same option that was used by the manufacturer, but experts recommend using more modern models. They are not only functional, but can effectively transform the panel. So, to choose from:

standard lamps A12-1.2 (article 21061-3709500);
standard lamps AS12-5-1 (article 2101-3746998);
LED light bulbs ShoMe SM T5 (article 3035);
LED light bulbs with high brightness SMD (article 182294);
Osram halogens (item 2473MFX6, 2721MF, 2886X).

Up to 19 devices will be required, depending on the machine modification and combination

Important! The car market offers a wide range of light bulbs, you can choose by technology, color, brand. It is important that the technical parameters of the devices are adequate to the car’s dashboard

Checking and replacing lamps

Now it’s time to arm yourself with a tester (the simplest Chinese one will do) and start ringing the light bulbs. To do this, put the device in resistance measurement mode (for LED light bulbs, the tester must be put in diode testing mode), and the lamps are removed one by one and dialed.

A tester is necessary for the reason that some light bulbs do not always light up and it is visually impossible to determine their serviceability. We won’t drain brake fluid or fuel from a VAZ to check the low level indicators of one or the other. If it is reliably known which light bulbs are working (for example, the illumination of dial gauges is normal), then these lamps can be left alone.

Nevertheless, I would recommend changing them all, especially if the VAZ modification has incandescent light bulbs (and this is almost always the case). Since it is unknown how long the old ones will last, and disassembling the instrument panel again, say, in a week is irrational.

After installing the new lamps, we connect the shield, without installing it in place yet, and check what can be easily checked visually: turn on the ignition, handbrake, turn indicators, etc. If everything is in order, then the dashboard can be assembled.

Let's get started

First of all, we remove the decorative trim of the radio (since the dashboard and radio are connected to each other, you will have to disturb the music system too), which is held on by fasteners; here it is better to use a screwdriver, threading it under the trim.

The main condition of work is caution. You need to start detaching the cover from the bottom edge

When the bottom edge comes off, you need to pull it towards you a little.

Now detach the top edge. Further:

Disconnect the wire directed to the cigarette lighter.
In the same way as we removed the cover from the radio, we remove it from the dashboard. Above the left and right edges we find two self-tapping screws. They need to be unscrewed. We unscrew the screws located at the top and bottom.
We remove the trim with a little effort (since it is also held on by fasteners, so the decorative plate will have to be rocked a little).
We disconnect all the wires: from the alarm system, from the clock, from the headlights and other things.
We remove the control panel itself, for which we unscrew the four screws on which it is held. In order not to damage the wires, it would be better to disconnect them on the one hand.
Now the most important thing. We remove the sockets of the light bulbs that have stopped burning. To remove the cartridges, you need to turn them counterclockwise with a gentle movement. We replace the defective lamps with new ones, wrap them and install the entire structure in the reverse order of disassembly.

We fix the lights and get acquainted with electrics

Bulb

The first thing that needs to be checked is the lighting lamp, since its burnout can cause the light to go out in the car interior.

Ceiling lamp

More than once, the cause of the malfunction was the lamp itself, where the contact group simply melted and closed, which caused a burnout or a blown fuse.

To diagnose it, you will need to remove it from the car and visually inspect it. It is also recommended to ring the contacts going from the lamp to the wiring.

Fuse and relay for VAZ-2114

Replacing the fuse can solve the problem.
The next cause is a blown interior lighting fuse. This part can burn out due to a short circuit, which for various reasons occurs in the on-board circuit. Often the short circuit is caused by a malfunction of the lampshade.

The interior lighting relay is marked with an arrow. Often the contacts burn out and prevent the light from turning on.

Wiring

Broken wiring may cause a malfunction

conclusions

There are few reasons for the malfunction of the interior light in the VAZ-2114, and every novice car enthusiast will be able to determine the cause of the malfunction. It is worth remembering that if a car enthusiast is not sure that he can deal with the problem, then it is best to contact a car service center.

Diagnostics

If problems arise with the vehicle's lighting equipment, the cause of the problem should be identified as quickly as possible and eliminated. The search should begin with the simplest and at the same time the most common causes. So, if one headlight on your VAZ 2114 does not light up, then most likely the reason is that the bulb of this headlight has burned out.

The simultaneous burnout of two light bulbs in both headlights also happens, but is extremely rare. As a rule, this occurs during sudden changes in voltage in the network and is accompanied by serious damage to other electronic equipment. Checking the serviceability of the light bulbs is very simple - you just need to replace them with new ones.

Burnt out light bulb filament

If, after replacement, the new light bulbs also refuse to work, then you should move on to the next stage - checking the condition of the sockets themselves. They very often become covered with a layer of oxides and stop transmitting current to the lamp. In order to fix this, you should carefully clean the nests with fine sandpaper or wipe them with a hard cloth soaked in kerosene or VD-40. If this also does not help, then move on to checking the circuit.

Inspection of sockets and contacts of headlight bulbs of VAZ 2114

In order to check the integrity of the electrical circuit, you should “ring” the wires leading to the headlights from the fuse box with a tester. If there is a signal, then the wires are working; if not, then there is a break and the wires should be replaced with new ones.

The next step of the test (although it can be done first) will be to check the fuses located in the common block. In this case, two 7.5 ampere fuses, labeled F12 and F13, are responsible for protecting the headlights. The first of them is in the right headlight circuit, and the second is in the left one.

The failure of one of them will lead to a breakdown of the light on only one side (this feature, along with the burnout of one light bulb, may be the reason why only one headlight is on). Solving this problem is extremely simple - you just need to replace the fuses with others designed for the same current strength.

Low beam elements on the fuse block

After all the methods described above have been tried, and you still have not been able to figure out why the low beam is not on and the high beam is on on the VAZ 2114, then you should check the last possible reason - the headlight switch button. First, you should check how the wires are attached to it - they have not come loose or oxidized. If everything seems to be working fine, then you need to check the button itself. The easiest way to do this is to replace it with a new one (fortunately, it costs a little more than a hundred rubles).

Finishing the conversation about possible malfunctions, it is worth mentioning an extremely rare but possible reason - a breakdown of the K9 relay (it is located in the common block). If a complete check of all electronic elements and replacement of the power button do not produce results, then this relay should also be replaced. Such a replacement should help correct the situation and return both headlights to operation.

Damage to the VAZ 2114 light switch button

Installation of new equipment

Now let’s figure out how to install an LED lamp on a car; for this we will definitely need a VAZ 2114 interior lighting circuit. This is done in the following sequence:

Remove the lampshade;
Unscrew the base of the case;
We connect the new lampshade;
Screw the LED lamp into place.

First we need to remove the original lampshade and disconnect the wires from it, all the contacts, we also need to remove the diffuser. The housing is screwed to the roof sheathing with four self-tapping screws; they are simply unscrewed and the housing is removed. Next, you need to take a new case and connect all the plugs in accordance with the diagram to the contacts that go to the battery. The new housing is screwed in exactly the same way onto the same four self-tapping screws, and the lens is snapped into place.

In this simple way you can update your car interior and make the interior lighting of the VAZ 2114 more comfortable and convenient.

INTERIOR OF THE CAR

The interior lighting is worth a separate discussion. The interior of the VAZ 2114 is illuminated using the following devices:

Interior lighting

Here the lamp lights up when the VAZ 2114 door limit switch, which stands on the racks and is pressed by the door itself, is triggered. There are also separate buttons for the passenger and driver to turn on this lamp if desired.

Step-by-step instructions for replacing light bulbs in the dashboard of a VAZ-2114

We release the decorative cover of the front panel. For this we need screwdrivers: a short Phillips and a flathead one. Lower the steering column to the lower position using the height adjustment lever to keep it out of the way. The photo shows the mounting locations for the casing:
Using a flathead screwdriver, pry off the decorative cap to the right of the row of switches. There is another fastening screw under it.
Also, remove the handles from the heater switch and damper control sliders by pulling them towards you.
If you have a car radio, you will also have to remove it. Unfortunately, you cannot do without complete dismantling. Arrows indicate locations for removal
Pull the front panel cover towards you. He must move. You don’t have to remove it completely - there will be enough space to access the fastening screws on the sides of the instrument cluster. Carry out the actions carefully
Unscrew the fastening screws with a long screwdriver. The combination will be released and you can tilt it towards yourself. Pull out the two blocks with wires. Don’t be afraid to mix them up - there is a color marking, and the asymmetrical shape of the connector will prevent you from connecting it incorrectly. The arrow indicates the location of the cartridge handle
On the back cover of the instrument cluster there are cartridge handles. Arm yourself with small pliers. This will make it easier to unscrew them. To release the cartridge, half a turn counterclockwise is enough. You can safely take out all the cartridges - they are the same. Next, you can check the lamps with a tester and replace the burnt ones, or replace them all with LEDs at once. Try to ensure that they fit tightly in the cartridge, otherwise the contact will be unreliable.
We reassemble in reverse order. We insert the cartridges into the seats so that the antennae fall into the grooves, carefully turn them with pliers until they stop. We connect both blocks to the connectors of the instrument cluster.
Let's check if all the lamps are working:
turn on the hazard warning lights - check the warning lamp and direction indicator lamps,
pull the headlight switch lever towards you - temporarily turn on the high beams, check the warning lamp,
turn on the dimensions - see if the scales are evenly illuminated, and if the warning lamp, if any, is on.

If everything works correctly, we fix the instrument cluster and the front panel casing, and replace the heater switch handles and damper controls.

Check the brightness and functionality of all devices

Congratulations, now the instrument lighting and warning lights are working properly, and you will always be aware of what is happening with the car. The overall aesthetics of the front panel will also improve - the evenly lit front panel looks beautiful.

Tuning the ceiling

Such a pleasant and exciting thing for a car enthusiast as do-it-yourself tuning is also possible with a courtesy lamp. Instead of the usual one, a lampshade with a programmable LED lamp is installed. It has advanced features:

selection of three brightness modes, this selection is made by switching the switch at intervals of one second, the last switching on is remembered;
shutdown delay 6-8 seconds with smooth extinguishing of the lamp;
automatic shutdown when the door is not closed or not tightly closed after 30 minutes.

The price for such a lamp is only about five hundred rubles, so the choice is obvious. The procedure for installing and connecting a lamp with a programmable LED lamp:

the plastic diffuser of the standard lamp is removed;
the wires are disconnected from the contacts of this device;
the four self-tapping screws holding the light housing on the body ceiling are turned out and the body of the old device is removed;
the LED illuminator is released from the plastic transparent diffuser cover;
the electrical wiring is connected to the plugs of the LED illuminator in accordance with the diagram;
the body of the new lamp is attached to the ceiling of the body in a regular place with self-tapping screws;
The plastic diffuser is fixed on the body.

It should be noted that such a lighting device produces brighter light, which in the dark is a good help for all people who are in the car.

Lighting in the VAZ-2115 is one of the most important components of comfortable movement by car at night. If the interior light does not work, the driver faces a lot of inconvenience.

The light emitted by street lamps will not help you find the desired item in the glove compartment, therefore, it is best for the driver to take care in advance that all the light bulbs and other components of the car’s electrical equipment work stably and reliably. But what to do in a situation if the lighting fixtures in the interior of a VAZ-2115 for some reason refuse to fulfill their duties?

Differences from its predecessor

Among the most noticeable modifications are visible parts of the body (see also wiring diagram for VAZ 21099 injector).

In particular, the designers changed:

the shape of the front wings;
the shape of the headlights and side lights;
back panel shape;
hood and trunk lid.

As a result, the overall dimensions of the car also changed, but it remained the same front-wheel drive, four-door, five-seater sedan car.

Advice: video materials from thematic forums where VAZ 2115 owners share their impressions of year-round operation of the car can serve as a good help in evaluating a car.

Assembly

When you have made sure that all the light bulbs on the VAZ 2114 are working correctly, you can begin assembling the panel. To do this, all the backlight wires are brought out onto the board and carefully attached using a soldering iron. They should also be attached to the board in a certain sequence, otherwise the backlight may not work. If the wires are too long, they should be shortened so that they do not bend and do not fall into the grooves of the latches between the dashboard and the dashboard during installation. Otherwise, the wires will easily get damaged.

When connecting the pointer drive, also make sure that they are not deformed. Now, the instrument panel can be inserted back into the grooves and fixed with screws. The indicator arrows must be set with the ignition off, at the zero mark. Next, the last check: turn the ignition key, and if everything works, then the replacement procedure was completed correctly, and the new backlight will please the eye. Well, if something doesn’t work, then most likely you damaged the wires when installing the panel on the dashboard. In this case, disassemble everything again and check the integrity of the wires.

Dashboard lamps

The dashboard provides the driver with a lot of useful information that allows him to monitor the condition of the car, the driving process, diagnose breakdowns in a timely manner and correct them. So, the panel light comes on for the following reasons:

The battery is not charging.
For one reason or another, the handbrake is stuck.
Not enough fuel in the tank.
The oil pressure has decreased (which indicates the need to urgently stop the engine to avoid more serious consequences).
Excess water in the filter. To prevent water from entering the pump, which could lead to damage, you need to drain excess water from the filter.
The fuel system is malfunctioning.
There was a failure in the propulsion system and much more.

As you can see, the panel lamps allow you to determine what is wrong in the car; if the lamps themselves fail, then you can miss a very important breakdown, which can even lead to an accident

This is why it is so important not to delay replacement (lamps cannot be repaired)

Today, the car market offers a wide range of lamps for the control panel, ranging from the standard version, which is cheaper but also has average characteristics, to modernized versions that give the panel, and therefore the entire atmosphere of the car, a different, more expressive atmosphere.

Professionals also advise replacing standard lamps with LEDs, which largely decorate the panel. So, we list several of the currently most popular options suitable for the VAZ 2114.

LED lamps Sho-Me SM-T5 (blue, white and red). Country of origin: Korea, price: 80 rubles. for a couple.
High-brightness SMD LED module – 20 rubles.
LED Sho-me SM-T5-cap-super (white) – 50 rub.
Halogen lamps from Osram and Philips cost approximately 40-80 rubles apiece.

As you can see, prices for lamps are not high. It is worth noting that replacement takes very little time, which we will talk about later.

Do-it-yourself overexposure of buttons on a VAZ 2114

Replacing the standard button backlighting on a VAZ 2114 will require the preparation of certain tools, materials, as well as some time. To work you will need the following list of necessary things:

soldering iron with a thin tip;
solder;
tweezers;
small knife or flat screwdriver;
LED elements of the desired color.

Which LEDs and in what quantities should I buy?

The buttons installed on the dashboard of the model in question come in old and new styles. In the first case, small light bulbs or LEDs are used as a backlight element, and in the second, boards with sealed SMD LEDs are used.

Bulbs, LEDs and SMD elements can be used as backlighting elements in buttons.

Each button is equipped with two LED elements: one is responsible for illuminating the button itself, and the second indicates the activation of a particular function. The exception is the low beam headlight button - it does not have a power indicator LED. Therefore, if you plan to replace the LEDs on all five buttons, you will need to purchase 9 backlight elements. The type of the latter can be determined only after disassembling the button. The old model requires 12 V LEDs with a diameter of 3 mm. The new sample uses elements marked 0805. When using standard LEDs, it is recommended to additionally install a resistor with a resistance of 500 Ohms to 1 kOhm along the power circuit (directly in the button), which will prevent the element from burning out.

To prevent the LED from burning out, it is recommended to install a resistor in series

How to remove buttons

To remove the buttons on the front console, do the following:

Remove the negative terminal from the battery.
We take out the plug of the on-board computer or the BC itself, if it is installed. To do this, just hook it with your finger and pull it towards you.
We put our hand into the hole formed and feel the back of the buttons.
Carefully press the buttons out.
We remove the blocks with wires.
Having completed the necessary actions with the buttons, install them in the reverse order.

Replacing the backlight of the front panel buttons

Since replacing LEDs on old and new button versions is somewhat different, each process should be considered separately.

Overexposure of old-style buttons

After removing the buttons from the instrument panel, perform the following sequence of actions:

Pull the top of the button and remove the lid that is pressed.
Insert a flathead screwdriver into the button and remove the inner part. You need to remove it carefully so as not to lose the springs.
Use a multimeter to determine the polarity of the LEDs.
We bend the leads and dismantle the LED element.
We bend the leads of the new LEDs and insert them into the button body, observing the polarity, after which we shorten the leads with side cutters to the required length.
Reassemble the button in reverse order.

Overexposure of new buttons

On modern buttons we change the LEDs this way:

We disassemble the button, as in the previous paragraph.
After opening we find a board with installed LEDs. We determine the polarity of the elements and solder them with a soldering iron with a thin tip.
In their place, we carefully install new SMD LEDs of the desired glow color.
We reassemble the button.

Modernization of the buttons for turning on the headlights and low beam

The buttons for turning on the headlights and low beam headlights are made as a single element. The absence of an LED indicating that the headlights are on low beam causes inconvenience to many motorists. This is due to the fact that it is often unclear whether the headlights work or not. To solve this problem, they resort to modernizing the button. In addition to the tools listed above, you will need a similar button from which the necessary parts will be removed. The finalization process itself consists of the following steps:

Remove the button from the panel.
Using a minus screwdriver, we pry up the keys, take them out and see that the LED is initially missing.
We disassemble the button housing by pressing on the latches with a screwdriver. At this stage the buttons should be in the pressed position.
We remove a couple of pins and contacts from the spare button, and then install them in the body of the element being modified.
We take out the board with two LEDs from the spare button and replace it with the board with one LED element.
Using a soldering iron, we connect the board to the new terminals.
To supply power to the new contacts, we connect the contacts with copper wire according to the photo.
Using a sharp knife or screwdriver, make a hole in the button cover.
We assemble the part in the reverse order and install it in place.

Shower controller. The lighting in the shower stall does not work. Part 1 – Fault diagnosis.

Some time ago, in my home, the interior lighting in the shower stall stopped working. Symptoms: when you turn on the light, the light bulb flashes for a split second and goes out; the light bulb does not react at all to subsequent on/off turns. After a few hours of downtime, history repeats itself. The lighting in the shower is controlled by a clearly Chinese shower controller “SHOWER CONTROLLER Z8688”.

Photo of the front panel of the shower controller.

The first suspicion naturally fell on the light bulb itself. But a test on a known working power source showed that the light bulb was in good working order.

Next, it was necessary to check the wiring and the controller itself. To check, it was necessary to dismantle the controller and remove all wiring from the shower. Unfortunately, it was not possible to take a photo during the dismantling process, due to the too small distance between the wall and the back wall of the shower stall. The removed controller with wires looks like this.

The photo shows a separate power supply and a control module with wires extending from it intended for controlled devices. I did not remove the front panel from the shower, since it was fixed in the opening of the shower body using sealant, and there was no desire to re-seal it in the body. Two wires (red and black) protruding from the control module, in the photo, led to microphone built into the phone's shower controller, but due to the fact that the microphone was tightly glued into the corresponding groove on the front panel, it had to be unsoldered.

Checking the power supply showed that everything is fine with it and it produces the required 12V as expected.

Next, it was decided to measure the voltage at the output of the controller to which the light bulb is connected. This is where all the fun began. The fact is that the multimeter at the output to which the light bulb was connected showed the required 12 Volts.

For comparison, I decided to check the voltage at the adjacent output, intended for external lighting, and it showed the same 12 Volts.

Checking the light bulb on this adjacent output showed that at the same voltage the light bulb works without problems.

Accordingly, the problem should be looked for in the current at the problem output. We check the amount of current passing in the circuit through the light bulb when connected to the “working” and “non-working” output. To do this, switch the multimeter to current measurement mode and connect it in series with the light bulb. Connection to the “working” output:

Connection to the “non-working” output:

Already when I was writing the article, I noticed that when I took a photo with the working output, I did not switch the multimeter from the microampere measurement range to the ampere measurement range, for some reason it showed the correct value but in a different order, in fact, after measuring it again, I got close to the calculated 0.76 A .

As a result, we see that the current at the problem output is 1.2 μA, while at the working output it is equal to: 0.76 A

We look at the diagram and determine the current path from the input to the non-working output. There is only one element in the current path: the relay.

This relay (HUI KE HK4100F-DC12V-SHG) is controlled by a 12 Volt signal. There is a suspicion that this relay has problems with the quality of the contacts of the switched circuit. To test this hypothesis, you should try to connect a light bulb bypassing this relay; to do this, we connect the input and output contacts of the circuit switched through the relay.

As a result, we see that removing the problematic relay from the circuit restores the operation of the light bulb.

Therefore, to repair this controller, you should replace the problematic relay: HUI KE HK4100F-DC12V-SHG. We search by model number, a new relay on the AliExpress website, order and wait for the parcel.

Order of Operations

Since the dashboard is interconnected with the music center, you will have to touch this system as well:

Remove the radio cover using a screwdriver, carefully threading the tool under the socket. First we pull it out from the bottom, then the top part of the lining. The electrical wires leading to the cigarette lighter must be disconnected. Now we find the screws on the dashboard and unscrew them. Remove the handles from the damper sliders and the heater switch by pulling them towards you. Now you need to remove the dashboard panel, it is held not only by screws, but also by other fasteners, so first you will have to loosen it a little. Now you need to disconnect the wiring from the panel: from the clock, from the alarm system, from the headlights and other devices. Note! Don't worry about wire tangles

There are color markings, and the shapes of the connectors will prevent incorrect connections.

Pull the panel towards you, but not completely. It is impossible to remove it completely, but it moves enough to provide access to the fasteners. We find 4 more screws on the control panel and unscrew them. On the back surface we find cartridges. It's easier to unscrew them with small pliers. Release the cartridge by turning it counterclockwise. Half a turn is enough. We do the same with the rest of the cartridges - they are all designed the same. We check the lamps with a tester and determine which ones are faulty. Or we change the entire combination, for example, to LEDs. We screw in the light bulbs tightly, remembering that they operate under conditions of vibration and shaking. We install all the cartridges in place. We use pliers again. Turn half clockwise until it stops. Now we connect the panel to the instrument connectors and check the functionality of all the light bulbs: from the ignition to the hazard warning lights. If everything works correctly, we fix the panel and perform the installation in the reverse order, before installing the radio cover.

For the procedure for replacing light bulbs in the dashboard of VAZ 2113, 2114 and 2115, watch this video.

How to remove the lampshade and replace the lamp

Since two lampshades are responsible for interior lighting in the VAZ 2114, we will change the light bulbs in both.

General lighting lamp

Let's start with it, since replacing the light bulb in it is simple and won't take much time. First, a little theory. You can turn on this lamp in two ways: by opening any of the doors (mode 1) or by pressing one of the edges of the lamp (mode 2).

That is, the lampshade in this lantern swings around the central axis and acts as a switch.

The principle of operation of the lamp switch
The numbers in the photo indicate:

Lantern body.
Glass shade.
Swing axis.

In order to remove the lampshade, it is enough to press the side of the housing at the swing axis so that the ebb on the glass comes out of the groove in the housing. This can be done with a flathead screwdriver or even your finger.

Pressing out the side of the flashlight body with your finger

First we remove this edge of the glass from the lantern, and the opposite one will come out on its own.

Removing the glass of the general interior lighting of the VAZ 2114

We remove the glass and observe the light bulb, which is clamped by two spring contacts.

Interior light bulb

We press the burnt out light device towards one of the contacts and remove it.

Removing a burnt out light bulb

We install a new one in place of the burnt one, simply snapping it into the contacts of the cartridge. We install the glass in the same way as we removed it: we insert one ebb on the glass into the groove of the body, snap the other one, slightly pressing the edge of the lantern with your finger.

Individual lighting lamp

Here we need a small flathead screwdriver to work. We insert the screwdriver into the slot, as shown in the photo below, and snap the flashlight out of the holder.

Removing the navigation light VAZ 2114

We take out the flashlight and see two blocks placed on the cartridge (marked with arrows). We remove them by simply pulling them out. In principle, you don’t have to remove the pads, but with them removed you won’t have to work with your hands suspended.

Power connectors can be removed for convenience

Now we press out the latches one by one, marked with arrows in the photo below, and gradually pull out the cartridge.

The latches, like the cartridge itself, are very fragile - ordinary organic glass. We squeeze it very carefully, take our time and be sure to take turns, gradually pushing out the cartridge. If the latch breaks, the cartridge can be thrown away.

The socket together with the light bulb is in our hands.

Removed lamp socket for individual lighting VAZ 2114

Slightly recess the lamp, turn it counterclockwise and remove it. We also recess the new lamp and turn it clockwise. We install the socket with the new light bulb in place, making sure that both latches work, put the power blocks on its contacts (polarity may not be observed), install the flashlight in the standard socket and press it until it snaps into place.

Operating procedure

Replacing the backlight on a VAZ 2114 begins with purchasing a set of LED lamps in the color you need. On the instrument panel, there are several sensors and indicators that require a certain number of diodes to ensure their normal visibility for the driver, especially at night. Therefore, before buying a set of lamps, calculate the required number of LEDs for each device. For example, a brake sensor requires 3 bulbs.

Location of light bulbs on the dash

It is advisable to buy with a reserve, at least 5 - 10 lamps more. Since, during installation, you can damage one of the circuits and the LEDs will not work. This often happens to those who are doing this work for the first time.

You need to start work by removing the instrument panel, as well as turning off the resistance. Next, carefully remove the old backlight bulbs from the factory sockets. On the reverse side of the VAZ 2114 panel, there are special sockets designed for installing LED backlight bulbs.

After the old backlight is removed, carefully grind off the heads of the LED lamps to the required size. If this is the first time this work is being done, then you will most likely need spare diodes. Next, when the heads are prepared, they need to be installed on the instrument panel. Replacement of light bulbs must be carried out strictly according to the same polarity as in the standard version.

After the diodes are in place, they need to be secured. Do not under any circumstances use screws for this. Scotch tape is also not suitable for this type of thing. When choosing a fastening element, you need to assume that it will heat up a little. Silicone glue is ideal for this. It will not damage the surface of the panel, thanks to its soft consistency, and will securely secure the light bulbs in the sockets.

Now, you need to check the quality of the work done. To do this, without putting the panel in place, turn on the ignition and look at the result. If everything works as it should, then the replacement was made correctly. If there are any inconsistencies, then you most likely have violated the polarity of connecting the backlight bulbs on the VAZ 2114. To fix the problem, you will need to find the connection diagram and double-check whether all the bulbs are in their places. If, after turning on the ignition, the backlight does not light up at all, then you need to check the integrity of the wires. The wires installed on diode lamps are quite thin and can easily break under the insulation or even break completely. So, be careful when handling them.

In what ways can you achieve original license plate lighting?

Recently, there have been frequent cases when LEDs are inserted into the ceiling instead of conventional lamps. Such lighting is bright and attractive, making the car original and interesting.

It is important that the lighting has a color acceptable by GOST standards and that the numbers are readable

It can be installed on a VAZ 2114 car in two ways.

First way

Replace standard incandescent lamps with LED lamps (they have the same contacts as in factory products).

It is also important to choose the right light bulbs; too bright ones will quickly fail and take up too much energy. It’s also not worth installing very expensive products, because the backlight will become very noticeable, distracting drivers from the road process

Low quality light bulbs can have various defects and quickly fail. So we buy light bulbs from trusted representatives and use them economically.

Second way

Install LED strip. To do this, you will need resistors - 3 pieces and the same number of LED strips. Their colors are very diverse, but it is best to choose white or yellow tones.

If a motorist, in spite of everything, wants to replace the standard backlight with LED, the following steps must be followed:

Solder a resistor to the positive end of the LED segments.
Attach small wires to its end and the negative side.
The result is a design with two contacts, which are powered by wires from the standard backlight.

To give the tape an original design, you need to take a piece of plexiglass and glue the strip onto it with silicone sealant. Next, we connect the wires of the tape to the contacts of the factory backlight lamps and make insulation.

At the next stage, we prepare the surface for installing the product:

remove the lampshades;
degrease the fastening side with solvent;
after drying, apply sealant and glue the LED strip;
We seal the tape along the edges and leave it until completely dry.

We check the operation of the design in action. If everything is functioning correctly, the job has been done effectively. In exactly the same way, you can illuminate the license plate around the edges, but this can lead to problems with the traffic police. Let's remember this!

LED lighting looks attractive both during the day and at night, making the car bright and original.

Repairing light in VAZ-2115

The first step is to make sure the light bulbs are working. Often the driver goes into the real jungle, looking for a breakdown when it is on the very surface. Using a screwdriver, unscrew the fastening elements of the lamp cover and remove the light bulb.

You need to make sure that there is a filament, or simply connect the lighting element to the battery. If the light comes on, you should proceed to the next stage of searching for the problem.

Very often, in cars of the VAZ family there is no light due to a breakdown of the lamp itself. There are often cases when the contacts inside the element melted, resulting in a short circuit. The lampshade can be easily removed using a screwdriver. It is possible to check its functionality by ringing the contacts. It is also recommended to conduct a thorough visual diagnosis, which very often provides answers to all the driver’s questions.

The consequence of a short circuit is the breakdown of the relay or fuse. It is enough to replace failed elements with new ones, after which the light in the VAZ-2115 interior will light up again. Breakdowns that occur in a car's electrical wiring are perhaps the most unpleasant and frightening malfunction for drivers. Not many people have the skill and experience to operate this car system. Therefore, if the reason for the lack of light lies precisely in the wiring, it is best to leave your “iron horse” in the experienced hands of an electrician. The difficulty in handling wiring is due to the fact that diagnostic operations involve ringing the wires from the power supply to the lamp or button.

Reasons for non-working interior lighting of the VAZ 2114

Below we will look at other reasons why the interior lighting may go out, including the dashboard lighting.

Light bulbs

Wiring

We inspect the wiring, the inside of the lampshade, and the contacts. If necessary, clean the contacts. If the light does not come on, you will need to test the wiring for a break. If a break is detected, it is recommended to replace this section of wiring rather than connect them. Because the connection leads to shortening of the wiring, and this affects the resistance. In general, the wires in the car should be the length specified by the manufacturer.

Circuit breakers

If, simultaneously with the interior lighting, the backlight of the ignition switch and the on-board computer display go out, then the problem clearly lies in the fuse.

Why change the backlighting of individual buttons on the VAZ 2114 dashboard

On the VAZ 2114, the illumination of the buttons for controlling the dimensions, low beam, front and rear fog lights, as well as the rear window heating is green from the factory. Over time, many owners get tired of this glow and there is a desire to replace it, make it non-standard. After making a decision about such modifications, you need to decide: do this work yourself or contact the service. Since the process of replacing button backlighting is not a complicated procedure, in most cases, car owners carry out such an upgrade with their own hands.

The standard green backlighting of the buttons gets boring over time.
