The dashboard of the VAZ 2114 injector 8 valves does not work why

The search for possible reasons why the VAZ 2114 instrument panel may not work periodically worries one or another owner of cars of this model. It’s clear that if you don’t see a single parameter on the dashboard, you can only drive, as they say, by touch. True, there are certain specialists who still managed to somehow crawl to the base without all the evidence, but somehow I don’t want to follow their example.

And is it necessary to create possible troubles for yourself and increase the risk of getting into an accident? I think no! In today's article I want to tell you about the possible causes of a malfunction in the VAZ 2114 dashboard, and give some ways to repair it yourself.

Light bulbs

By bulbs we mean LED lights, which are often connected incorrectly, which is the reason for the dimming of the light on the dashboard. In this case, all contacts in the backlight are checked.

If we talk about incandescent lamps, then even the breakage of one element leads to the fact that the backlight stops functioning. The test is carried out with a tester, ringing the entire circuit.

To summarize, we can say that the main reason for the lack of backlight on the dashboard is often a short circuit. It will not be difficult to inspect and, if necessary, repair yourself. But you can also contact a car service center, where such work will be carried out more professionally.

Instrument panel device

On the instrument panel of the VAZ-2112 there is:

1. Speedometer.
2. Tachometer.
3. Fuel level indicator.
4. Direction indicator.
5. Liquid temperature indicator in the cooling system.
6. Control lights.
7. Blocks for connecting wires.

Before you start doing any work on the dashboard, it is recommended that you familiarize yourself with its pinout. In other words, you first need to understand where each wire goes and what it is intended for.

Pinout and instrument panel diagram

Instrument panel pinout

1 — fuel reserve warning lamp; 2 — instrument cluster lighting lamps; 3 — right turn indicator lamp; 4 — left turn indicator lamp; 5 - backup warning lamp; 6 — coolant temperature indicator; 7 — indicator lamp for external lighting; 8 — control lamp for the carburetor air damper; 9 — oil pressure warning lamp; 10 — parking brake warning lamp; 11 — battery charge indicator lamp; 12 — tachometer; 13 — control lamp “CHECK ENGINE”; 14 — speedometer; 15 — brake fluid level warning lamp; 16—hazard warning lamp; 17 — control lamp for high beam headlights; 18 — fuel level indicator.

Troubleshooting

There are several most common problems that may cause the instrument panel on a VAZ-2112 to not work. These are:

1. The backlight does not light up. Here you will need to check all contacts, wiring and its condition. Fuses or light bulbs may also simply blow out. There can be many reasons for this, and therefore it will not be possible to quickly solve the problem. We need to understand everything in detail. We had a case where all the instrument panel backlight diodes burned out at once. I had to change all the light bulbs.
2. Node failure. This is the most serious problem of all. In this situation, all devices stop functioning. In order to fix the problem, you first need to check fuse No. 1 (5 amps initially, but we have 7.5, 5 amps were knocked out).

   You can find it on the mounting block. If it is burnt out, you just need to replace it. It is also necessary to discover the reason why it failed. Usually a short circuit in the wiring leads to such consequences.

3. The arrows are jumping. Here the main reason is that the mass on the shield is bad. To get to the ground wire you will need to pull out the car radio. Such a wire may be shifted to the side when installing, for example, an alarm system. Therefore, if there is an alarm in the car, and there is no wire under the radio, you need to look for it in another place. It may be behind the upholstery in the area of ​​the driver's left foot. Also, the ground wire may be damaged during the installation of a new radio. You need to take the time to fasten such a wire to the car body.
4. Problems with the instrument panel. Here you will need to check if everything is fine with him. To do this, you need to pull it out from its seat, but do not disconnect the wires. You need to check the voltage in the wiring. Be sure to also look at the back of the device to make sure that the conductive paths are not damaged.
5. Cigarette lighter. Often the instrument panel may fail due to the cigarette lighter (for information on replacing the cigarette lighter, see “replacing the cigarette lighter on a VAZ-2112 with your own hands”). Drivers can use various additional devices through this connector, for example, phone chargers. As a result, a large amount of energy is consumed, which causes fuses to blow. For this reason, the instrument panel may also not work correctly. In this case, you need to check fuse F18 and replace it if necessary.

Which bulbs are suitable for the 2114th model

In general, the current legislation provides for quite serious sanctions against motorists who dare to make any changes to the design of the vehicle at their own discretion. In accordance with the rules, they are obliged to replace components and assemblies only with analogues of those chosen by the manufacturer. Failure to comply with this requirement provides grounds for punishment of the driver.

Thus, more and more owners are installing LED lamps on their 2114 Ladas instead of the standard halogen ones. This choice is easy to justify. In particular, they:

• consume approximately 8-9 times less electricity, which means the load on the on-board power system is reduced;
• last 5-10 times longer;
• give brighter light;
• practically do not heat up.

Finally, the dashboard looks much more attractive, because the light bulbs can be of different colors - blue, red, green, etc.

The problem is that LEDs cost about twice as much, but this disadvantage is more than compensated by their longer lifespan. In addition, LED lamps are becoming cheaper every year.

Why doesn't the instrument panel light come on?

I'll give you an example from my life. I went fishing in the summer with my friend in a VAZ 2115 car. On the way, before arriving at the place, the instrument panel lights stopped lighting up

The malfunction would seem insignificant for daytime, but in the evening and at night the driver in this situation is unable to concentrate his attention on the instrument readings, which means it was necessary to eliminate the malfunction

What to do in this situation, where should you look for the cause of the malfunction? Spare bulbs were available, fuses were missing. Or maybe the reason is not in the fuses, but in a break or lack of contact? In general, it’s impossible to immediately figure out where to start. That is, we asked ourselves a single thought: How can we determine the malfunction in this case?

VAZ 2115 fuse diagram: even a child can figure it out

Much has been said about the importance of such a small component of automotive wiring as a fuse. Indeed, the smallest part made of fusible metal, which melts and breaks the circuit when the permissible values ​​are exceeded, can protect the car from short circuits, local power surges, and even fire

And besides, even a small child can actually figure out the VAZ 2115 fuse diagram

And besides, even a small child can actually figure out the VAZ 2115 fuse diagram.

What does a car enthusiast do if his beloved “iron horse” suddenly stops responding to individual orders? The windshield wipers or power windows suddenly stop working. What to do? Change the motor, and maybe the entire element, so to speak, as a whole? In fact, the first thing you should check is the fuses. It may well be that the whole problem is a spare part, the cost of which is comparable to a ticket for a city regular bus.

Location of relays and fuses in the mounting block: K1 – relay for turning on the headlight cleaners; K2 – relay-interrupter for direction indicators and hazard warning lights; K3 – Windshield wiper relay; K4 – lamp health monitoring relay; K5 – power window relay; K6 – relay for turning on sound signals; K7 – relay for turning on the heated rear window; K8 – headlight high beam relay; K9 – relay for low beam headlights; F1-F20 – fuses

Of course, replacing fuses only takes a professional a couple of minutes. However, you still need to get to a specialist. What if the ignition doesn't work? Order a tow truck? Expenses, expenses. But often it is enough to check the functionality of the fuses responsible for a particular block and spend the same five minutes replacing them. And your car will be like new again, and a visit to the service station can be postponed until there are really serious breakdowns.

The fuse box in the VAZ 2115 is hidden under the hood, on the driver's side. By opening the cover (it is secured with two simple latches), you get access to the fuses themselves and special tweezers, which are stored right there in the mounting block. It is very easy to decipher the designations of the relays and fuses located in the mounting block, especially if you have a diagram at hand. Relays are designated by the letter “K”, fuses by the letter “F”, the number allows you to determine the area of ​​​​responsibility of a given fuse or relay; the value in “A” (amps) means the maximum voltage level for this fuse. So, next to fuse F2, which is responsible for the turn signals and the operation of the hazard warning lights, a level of 10A is indicated, that is, this is the load the fuse can withstand. Excessive voltage will damage the fuse, but will preserve the integrity of the system itself.

How to identify a malfunction

There was no indicator screwdriver, just a small flashlight and some thin copper wire. It was decided to identify a blown fuse in the mounting block by dialing. For this diagnostic method, it was necessary:

1. disassemble the flashlight;
2. cut one wire (in the flashlight circuit);
3. add two small pieces of wire (about the same cross-section) to the ends of the cut wire;
4. close the flashlight key (turn on the flashlight).

As a result, the result was a homemade device for testing individual circuits and, in particular, for testing fuses in the mounting block located under the hood on the driver's side. You, of course, understood how to use such a “device” (two wires with bare ends are taken, which are subsequently connected to the fuse contacts). The two wires brought out from the flashlight serve as “device probes”, when closed, the flashlight light comes on.

A blown fuse was subsequently found (identified) in the mounting block, this is a 7.5 A fuse F10, which is responsible for lighting:

• devices,
• engine compartment

and car number.

There was no spare fuse of the same type in reserve and, accordingly, the question arises: How can I replace the fuse?

How can I replace the fuse?

In the current hopeless situation, it was necessary to install a piece of thin copper wire instead of a fuse, after which the instrument panel and other current consumers began to work properly. Of course, this is not the best way to fix the problem, but nevertheless, after fishing we arrived home safely. Upon arrival home, the car driver installed a working fuse of the appropriate color.

Replacing the fuse on a VAZ 2115

Each fuse that is included in the electrical circuit of the car must correspond to its rated current value, which thereby protects current consumers for a particular circuit from malfunction.

fuses for vaz 2115

To make it easier to find a fault both in the lighting and in other consumers, the manufacturer provides colors for the fuses. The schematic representation of the mounting block (Fig. 1) clearly shows the location of the fuses and relays included in the electrical circuit of the car.

rice. 1

Fuse colors

There is no need for any explanation regarding the color marking of the fuses; everything already looks quite clear. Each fuse with a certain color will correspond to the maximum current value.

Let’s say that if the power windows malfunction, you must first check fuse F6 with a maximum current value of 30 Amps, and then (depending on the circumstances), check the remaining connections in this circuit.

That's all for now. Follow the section.

The backlight of the VAZ 2114 instrument panel does not light up: do-it-yourself repairs

The dashboard on the VAZ 2114 allows the driver to control engine data, monitor the remaining amount of fuel, his speed, and other data. The panel should be maintained in working condition so that the backlight not working does not cause discomfort, and the sensors show real values.

Bright backlight

But quite often, VAZ 2114 owners discover that the instrument panel lights do not light up. If such a situation occurs, appropriate action should be taken immediately to eliminate it.

Why the instrument panel does not work

Disassembled dashboard

The first thing you need to figure out is why the instrument panel on the VAZ 2114 does not work. If the backlight goes out, there may be several reasons for this:

• The incandescent lamps burned out, the LED lighting groups stopped working;
• The connectors have oxidized;
• The electrical wiring is faulty, there are defects in the circuit;
• The fuse box has stopped working;
• Damage appeared on the common contact board;
• The dimensions system is damaged;
• There is no minus on the body (weight).

Removing the dashboard

To replace the light bulbs in the dashboard of the VAZ 2114, it will first have to be dismantled. Without this action, you will not be able to access the problematic device.

Panel disassembly diagram

Therefore, now we’ll figure out how to disassemble the instrument panel on a VAZ 2114:

• Unscrew the three screws, remove the trim and the protrusion from below. It comes out of your car's body bracket;
• Now remove five more screws located on the right console trim;
• Remove the screen; Disconnect the negative terminal from the battery;
• Disconnect the wiring harness connector from the cigarette lighter;
• Remove the handle from the lever;
• The fasteners for the electric fan of the heating system, that is, the stove, also have to be removed;
• Unscrew the steering wheel block bracket fixing bolts;
• Remove LEDs, lamp sockets and decorative inserts on the panel;
• Unscrew the hydraulic corrector illumination lamp. For this you will need a key for 21;
• Now all that remains is to remove the screws at the top and bottom.

Thus, we figured out how to remove the dashboard on your VAZ 2114. Be sure to cover the electrical circuit with something after the measures have been taken to prevent moisture, dust and all kinds of contaminants from getting there.

Proceed to replace the lamps that turned out to be faulty. At the same time, many are interested in how many light bulbs are in the dashboard of the VAZ 2114. There are 13 of them, but only 8 can be replaced. Do not forget to clean the contacts if there are traces of oxidation on them. In some cases, it is not the lamp itself that has to be replaced, but the socket for it.

Selection of light bulbs

Wiring ringing

Today the market offers a wide range of lamps that can be used for the dashboard of the VAZ 2114. Among the most well-proven devices, we note a few. Their name and cost are presented in the 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.

1. Buy a set of LED lamps, having previously calculated the number of devices needed for each sensor.
2. 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.
3. Connect the power and check how the new backlight works.
4. 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.
5. Make sure the instrument panel arrows are positioned correctly. When trying to quickly complete a job, they often become deformed and bent.
6. The backlight structure is fixed with screws.
7. The power for the LEDs is connected to the power supply for the light bulbs, the arrows are put on and set to zero.
8. 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.

How to disassemble the dashboard of a VAZ 2114

Before embarking on this complex process, the driver must carefully familiarize himself with the design and arrangement of the instrument panel on his car. When disassembled down to the cogs, it looks like this:

If you carefully study this diagram, it becomes clear how to remove the panel on a VAZ 2114. Having determined the order for yourself, you can begin the process.

Using a Phillips screwdriver, you need to unscrew the three screws holding the left console screen

For convenience, when doing this work, it is better to use a screwdriver with a short handle and blade. When removing the screen, carefully remove the lower edge of the trim from the body bracket. The right console screen is secured with five self-tapping screws. Using a Phillips screwdriver, carefully unscrew all the screws while holding the trim with your hand. Remove the screen without allowing it to get caught in the wiring harnesses that are hidden behind it. Disconnect the ground from the battery by disconnecting the connectors. If your car has a radio, disconnect it from the main bundle of wires by pulling out the connecting block

If there is no radio installed on the car, then simply pull the wires out of the panel; they should be closed with a plug. Be sure to turn off the cigarette lighter and remove the socket with the ashtray light bulb. Remove the handles from the heater damper control levers. To make the process easier, pry them off with a flat-head screwdriver. Despite the apparent simplicity of this item, removing the handles from the levers can take a lot of time. To do this, a clear example is given of how this should be done on a removed unit. Remove the electric heater fan handle by simply pulling it towards you. Unscrew the self-tapping screws with a cross-shaped head that secure the instrument panel to the brackets on the right and left with a screwdriver. In the window on the instrument panel, where the instrument unit is located, there are two self-tapping screws at the top and two at the bottom - under the window. It is necessary to turn them out, loosening the cover (2) and the shield (8). Pull out the plug and unscrew the self-tapping screw located behind it. Remove the two self-tapping screws from below that hold the trim and remove it. Having marked the wires suitable for the switches, disconnect them. Unscrew the bolts from the steering wheel bracket. Use an “8” key to unscrew the screws of the lower bracket mounting. Unscrew the self-tapping screw and remove the light guide. Remove the fasteners from the heating control unit and remove the cartridges from the back of the unit. remove the decorative insert, removing all external parts. Unscrew the nuts with a key set to “21”. Remove the hydraulic corrector illumination. Unscrew the upper and lower fastenings of the panel, and remove the fastening to the cross member on the left side. Now you can remove the VAZ 2114 torpedo. Installation is done in the reverse order.

In order to clearly see the whole process in motion, you can watch a video on how to remove the dashboard on a VAZ 2114.

Finally, the panel itself is removed. The panel is assembled accordingly in the reverse order.

It is important to remember the sequence of actions if you are performing this procedure for the first time. When disassembling and assembling you need to be extremely careful and attentive.

Hi all. Today I will write about the experiments that I have been doing for the past two weeks. The idea to re-illuminate the dashboard with boards belonged to DMMC, and I agreed because 2 LEDs in my dashboard burned out. One is off, the other is blinking and there is a disco on the dash. It was also necessary to make a smooth ignition so that it would be completely good. While driving, I found diagrams for smooth operation and tidying, if you look hard enough, you’ll find them too. I went to buy textolite, diodes, resistances and other necessary ingredients. Required: - Textolite; — Diodes 3528 white; — Resistance 330 Ohm (For white LEDs, for others you need to calculate); — Soldering acid, solder, citric acid, hydrogen peroxide and nail polish remover (or whatever you have on hand to remove toner from the chip) Printed out the diagrams on glossy paper,

Tidy 2115: description and purpose of buttons and knobs

If everything is simple with the levers on the steering rack, there is a headlight position switch and a turn signal switch on the left. Buttons are more difficult.

On the dashboard, the main keys are placed in a separate “strip”. To understand the essence, we present their decoding from left to right.

1. Switch for outside parking lights.
2. Activation of low beam headlights.
3. Front fog lights.
4. Rear PTFs. If not installed, reserve.
5. Rear window heating button.

Lada 2115: the oil light on the center panel is on

If an icon in the shape of a watering can appears on the console, this indicates that there are problems in the engine lubrication system. This is caused by a drop in the oil level in the crankcase or a pump malfunction. If the engine is old, the problem may be caused by clogged oil lines.

What does the exclamation mark on the Lada 2115 tidy mean?

On the "tag" the symbol is used in only one form - a red indicator in a circle. The icon indicates a malfunction in the vehicle's brake system. If this symbol lights up while driving, stop and find the cause of the breakdown. Usually it is enough to add fluid to the expansion tank or replace worn pads.

The battery light on the dash is on 2115

A red battery icon indicates that the battery is not charging properly. A complete diagnosis of on-board systems associated with the generator set and its wiring is required.

Functionality check

After completing the replacement, install the panel inside the car, connect the connectors, but do not rush into final fixation - you still need to make sure that everything works properly.

To do this, turn on the ignition and see if the backlight turns on. Then check whether the indicator lights responsible for:

• hand brake;
• oil pressure;
• fault signal, etc.

Then test the turn signals, headlights and side lights. If everything is in order, then complete the panel assembly.

Lada 2112 ᵀᴴᴱ ᴼᴿᴵᴳᴵᴺᴬᴸ › Logbook › WHY VAZ 2110-2112 DEVICES DO NOT WORK

Mikhail Grebenkin, 27 years old I drive a Lada 2112 ᵀᴴᴱ ᴼᴿᴵᴳᴵᴺᴬᴸ (before that - Lada 2108) Voronezh, Russia

The instrument panel of the VAZ-2110-2112 contains: speedometer, tachometer, fuel level indicator, coolant temperature indicator, 12 different indicator lamps, 6 dashboard backlight lamps, one reserve socket for the indicator lamp and two wire connection blocks. It is very easy to distinguish the pads, the one that is white in electrical diagrams is designated as X1, and the one that is red is designated as X2. The instrument panels themselves, installed on VAZ-2110 cars, can be of two types: the old model, where the instruments are placed symmetrically, and the new model, with fuel and coolant level indicators shifted to the right side of the dashboard.

The biggest malfunction of the instrument panel will be its complete failure. In this case, neither the control lamps nor the devices themselves work. The driver, first of all, needs to check the 15 amp fuse F6. It is located in the mounting block. If it burns out, it is necessary to look for the cause of this phenomenon, otherwise the new one installed will repeat the fate of the previous one, that is, it will also burn out. The cause of blown fuses is a short circuit in the electrical circuit.

There are times when instrument needles begin to jump along their scales from minimum to maximum. Most likely, the reason for such actions of devices will be poor contact with ground. The ground wire coming from the instrument panel is attached to the partition separating the engine compartment from the passenger compartment. You can find it by removing the radio from the socket. But if an alarm was installed on your car, then it is quite possible that the fastening of this massive wire, for ease of operation, was moved to another place, more accessible. Usually, alarm installers move it behind the interior trim in the area where the driver’s left foot is located. A similar picture can occur when installing a radio. When connecting its negative wire, the ground wire of the instrument panel was unscrewed, and then it was wrapped poorly, as a result of which it weakened under the influence of vibrations transmitted to the car body. They wrap it poorly because it is not very convenient to do so.

If everything is in order with the fastening of the ground wire, then you will have to check the instrument panel itself. To do this, you need to pull it out as far as possible from its mounting location without disconnecting the wires going to the pads. You will need to check on the white block X1 the ground wire going to contact 1, and at the same time check the voltage on contacts 6, 9, 10, it should be equal to 12 volts. Look, on the back side of the instrument panel, for the integrity of the paths along which electric current flows to the corresponding consumers.

Another cause of instrument panel failure may be the cigarette lighter. The fact is that through this socket, some drivers connect additional devices, such as: a cell phone battery charger, an electric tire pump, or a car interior vacuum cleaner. Considering that these consumers require high current, either the cigarette lighter itself fails or fuse F19 blows, which leads to failure of the instrument panel. By the way, you can also disable the cigarette lighter by holding it in the on position for a long time. In these cases, you can make the instrument panel work by disconnecting the cigarette lighter connector if fuse F19 is intact.

In principle, the driver himself can eliminate all malfunctions associated with a complete failure of the instrument panel. For this, he does not need any additional knowledge in electrical engineering. The only thing he needs to know is the probable causes of failure of the instrument panel.

Previously “Blind spot” - learning to keep control Next Why does the VAZ 2112 start and stall

The most common breakdown

Before digging into the inside of the car, check how securely the ground wire leading to the front panel is secured. A restless passenger in front often simply pulls him out of his place with his feet. To prevent the situation from repeating itself, after fastening it is worth insulating the wire from reach.

Its signs are very characteristic:

• All indicators do not work: speedometer, tachometer, odometer, fuel level recorder, coolant temperature sensor;
• The rest of the equipment - optics, radio, even the panel backlight - turn on normally and do not act up;
• The ignition works properly, the car does not refuse to start;
• Fuse F3 is almost 100% blown. It is located in the mounting block and will have to be changed. But first you need to find out why it was covered, otherwise the new one installed will suffer the same fate. In most cases, a short circuit is to blame for burnout. On well-used VAZ-2114, the fuse often blows after each wash. Instead of carrying a spare one, you need to figure out where moisture is getting into it.

If the fuse is intact , this is not a reason to immediately leave it alone. It would be a good idea to remove it and check the contacts: if the fuse is live, but the terminals are oxidized, the circuit will be interrupted, and the device will stop showing any signs of life.

The next weak link : It is the ignition relay. It is located to the left of the steering column, fixed on a pin, so to speak, upside down. You need to remove it and try to make direct contact with the wires. If there are obvious signs of revival on the instrument panel, it immediately becomes clear that the time has come to change the relay.

Possible malfunctions of the VAZ 2114 speedometer

The basic, historically established function of the speedometer remains necessary only to comply with traffic rules. Information about the vehicle speed is used by the electronic control unit to maintain stable power mixture supply conditions.

Symptoms

Characteristic signs indicating incorrect operation or breakdown of the speed meter are:

Possible reasons:

• fuse F19 in the mounting block has blown;
• a worm gear made of plastic is destroyed (worm, gears);
• the end of the cable that engages the gearbox transmission mechanism has broken off;
• bent, the cable casing collapsed;
• break in the signal and power wires of the speed sensor;
• oxidized, contacts in the connector disappeared;
• problems with the sensor electronics;
• the speedometer on the dashboard is out of order;
• wheels with a different outer diameter were replaced;
• the device has been replaced by another, calibration has not been done;
• the speed sensor does not match the gear ratio (external color difference).

Wiring damage

One of the unwanted breakdowns is damage to the wiring. Small contacts, resistors and plugs are difficult to repair without tools. Lack of power to the connectors and bulb sockets leads to their malfunction. As a DIY repair attempt, you can disconnect the plugs and connectors, and then clean all contacts from oxides. In rare cases, this procedure can restore contact.

The backlight of the VAZ 2114 dashboard is not a key design component, but its absence seriously complicates the process of operating the car at night. When replacing lamps, you can carry out overexposure procedures and replace standard elements with LED ones. In addition to increased brightness, you will get a longer service life. The photo above shows a detailed diagram of the connections of the VAZ 2114 instrument panel.

Potential problems

Before changing the light bulbs on the instrument panel of a VAZ 2114, it is worth knowing that this brand of car encounters certain difficulties that are typical for most of these cars. Users may encounter similar problems after a short period of use.

Often, at some point the car owner notices that the backlight on the dashboard does not work. The factor may not be noticeable to those who use the car during the day, but for drivers who operate the car at night, this incident is critical. This factor can lead to an accident or provoke an emergency situation on the road.

Timely replacement of light bulbs in the VAZ 2114 dashboard helps minimize the potential threat. To perform the operation, you will have to dismantle the front part of the device in order to successfully reach the necessary contacts.

The side lights are located in the main headlights, but many owners modify the lighting and install additional diodes in the turn signals. In each case, the design contains a fuse that protects the electrical circuit. Its failure means a malfunction of the entire circuit. If the rear left indicator does not light up, check the condition of the indicator under the F10 marking.

The fuses for the left and right side of the side lights on the 4 are located in the mounting block. Fuses marked F10 and F11 protect the left and right sides of the lamps, respectively. The photo shows the location of each of the fuses in the mounting block of the new model.

The fuse marked F10 is responsible for the left side of the dimensions, and F11 for the right.

The simultaneous cessation of lighting in the listed places indicates a malfunction of fuse F10, whose task is the left side of the light bulbs on the machine. When considering the reasons why the dimensions on the VAZ 2114 do not work, do not be lazy to check the condition of other fuses for integrity. Normal operation of electrical appliances simplifies the operation of the machine.

Finding the cause and restoring the light

Rear fog lamp fuse.

What do the glove compartment and rear foglights have to do with it? The 15-amp fuse F21 is connected to the glove compartment lighting and the battery saving mode module. If a short circuit occurs in the circuit, it is this fuse that blows, which supplies power to the main battery block fuse.

This fuse is marked ef1 (rated 30 A) and is installed in the mounting block under the hood of the car. In addition, it protects circuits F13, F14, F15, F16, F21, F22, F23 and F24, and these circuits contain the side lights and dashboard lights.

Therefore, to troubleshoot the problem we do the following:

1. Check to see if the glove box light is working. If it doesn’t work, we disassemble the glove compartment (after having removed the negative terminal from the battery), connect the power wires to the switch and the light bulb, if necessary, look for a break or short circuit and fix the problem.

   First, look at the glove compartment lighting.

2. We check the integrity of fuses F4 and F6, they are located on the left, at the end of the front panel in the cabin, in the interior mounting block. If necessary, replace them with ones of equal nominal value (10 A).

   We check fuses F4 and F6 for integrity.

3. We check the integrity of fuse F21 with a rating of 15 A, which, according to the diagram, is responsible for the operation of the rear fog lights.
4. We check the 30 A fuse EF1, which is installed in the engine compartment mounting block, and if necessary, replace it with a similar one.

   There is also a fuse box under the hood.

5. Next, you need to get to the instrument panel and check the integrity of the lamps on it.

6. If all the fuses are intact and the lamps too, but the problem is not solved, most likely the problem is in the energy saving module. Its catalog number is 96408390, it is located in the engine compartment mounting block. It is extremely rare for a module to fail, but it is possible.

Private situations

General signs do not always indicate specific breakdowns. There may be exceptions.

If individual devices refuse to work, it is quite possible that this is their personal problem. You'll have to parse the specific pointer. It may have a cracked gear that needs to be replaced.

Also, why doesn’t the instrument panel of the VAZ 2114 work? If the fuel gauge and tachometer are capricious (either they function, or they don’t react at all), the contacts and the mounting block are normal - you need to do a small check.

Reset is pressed and held, and the ignition is turned on at the same time. Raised arrows indicate the need for further searches. Lifeless - that microcracks have appeared in the shield itself. You will have to remove it and examine all soldering and traces under a magnifying glass. In principle, these are all the main options. If calling all the listed components and parts did not lead to the revival of the instrument panel, your case is individual, and you will have to determine the situation in the company of an experienced auto mechanic.

Hard case

Until now, situations have been sorted out when the torpedo still showed some signs of life. If non-working power windows, turn signals, and windshield wipers have been added to the devices, the issue is no longer a matter of relays and fuses.

• The contacts on the ignition switch are burnt. In principle, after installing the relay (even on the VAZ-2109 version), this problem rarely arises. However, the possibility remains. The lock is removed, the contacts are checked and, if necessary, cleaned;
• Mounting block. There may be burnt tracks on its board. The only thing that will save you is replacing it with a new one. However, the cost is by no means astronomical, and the installation is available as a standalone option.

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.

Solutions

So, when all the main reasons are, so to speak, “in the face,” you can try to determine the exact location of the breakdown, and also fix it yourself. As always, it is worth noting that if a motorist does not know the design of the car or is not confident in his abilities, then it is recommended to contact a specialist car service center.
