What to do when the light suddenly goes out in the interior of a VAZ-2114? Many motorists will say - go to an electrician and let him sort it out. But we will try to find the cause and methods of elimination when the interior lighting goes out ourselves.
Car electrical circuit diagram, which must be studied before starting work
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:
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 that needs to be checked 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
Broken wiring may cause a malfunction
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.

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.
Schematic electrical diagrams, connecting devices and pinouts of connectors
The fourteenth model was previously equipped with a 1.5 liter eight-valve engine, borrowed from the VAZ 2111 model with an injector. A little later it was replaced by the VAZ 11183-1000 version, which complies with the Euro-3 standard. The VAZ 2114 injector received a more powerful engine, and this is one of the reasons that the wiring of the 2114 has also changed.
A wiring harness has been added for connecting to the electronic switch. A harness has also appeared for connecting to the ignition module terminal.
Functions and types of fuses
The protective element protects equipment from damage and combustion during overloads. When large currents enter equipment that is not designed for them, or when there is a short circuit, a section of the circuit is at risk. Therefore, fuses are included in the circuit, which, in the event of a threat, break and open the contact.
This is achievable thanks to the unique design of the element. It is protected by a case made of special glass or heavy-duty ceramics. Contacts, working thread and fusible element are built inside. Contacts are designed to connect to a circuit. A fusible element, made of a conductor or an alloy of current-carrying metals, melts when an excess current passes through it. When the circuit instantly breaks, an electric arc is formed, which carries the danger of a spark. In order to extinguish the arc, a thread is built into the fuse.
There are several types of fuses based on voltage and amperage. The element is characterized by two current values: the rated current of the insert and the rated current of the housing, sufficient to destroy the fuse. The VAZ 2114 uses low-voltage fast-acting protective elements.
Depending on the purpose of use, there are two types of fuse markings: g and a. The former is able to withstand exceeding the rated current for a long time. This is necessary to start electric motors. This type of protective elements can protect against both overload and short circuit. The second class of protective devices is intended only for protection against short circuits and high currents.
Depending on the current the protective element is designed for, it is customary to designate the protective element in different colors, this helps to quickly navigate when troubleshooting electrical circuits.
Blue devices open the circuit when 15 A is exceeded, yellow ones - 20, and white ones - 25. The most powerful fuse is green. It is rated at 30 A.
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.

What do VAZ fuses protect?
In order to quickly identify the causes of malfunctions in the VAZ 2114 electrical system, it will be useful not only to know the color codes. Knowing the purpose of each of them, the process of identifying a breakdown is accelerated.
Rated currents of the Lada electronics:
ZE F1 and F2 are designed for a rated current of 10 A. The first protects the rear fog light bulbs from burning out. The object of protection of the second is the light direction indicators, emergency lights and relay-breakers of these devices.
Protective elements F3, F4, F8 - F15 are manufactured for a maximum amperage of 7.5 A. They are designed to protect interior light bulbs and trunk lighting, and the engine start light on the instrument panel. One of them protects the rear window heating circuit. Individual elements prevent a short circuit from occurring in the circuit of the left and right fog lamps. F10 is responsible for breaking the circuit of the license plate lighting bulbs, the dashboard and the lighting under the hood. The remaining 7.5-amp protective elements protect the head optics lamps (dimensions, low and high beam headlights).
An element with a current of 15 A is necessary to protect many elements, the main ones of which are: the generator winding, oil pressure lamps, and brake fluid temperature. The 20-amp fuse F5 is responsible for the sound signal and the electric motor that rotates the cooling fan.
The most powerful, 30-amp electrical circuits protect the contacts of power windows, electric heater motors, windshield washer and headlight cleaners.
Why the light in the VAZ 2114 interior does not light up: what is the fault of the lampshade
- Check the functionality of the lamp. If it does not light up, the fuse is faulty and should be replaced. If the brake light works properly, then the fuse is fine and you need to look further.
- Check the condition of the light bulb, if it is working, then you need to check the contacts and limit switches on the door pillars. If an LED lamp was installed, then change the polarity; there could be a mix-up during installation.
- It is necessary to measure the current at the contacts, whether it flows or not. If there is no current, then you need to ring the entire circuit; a breakdown in the wiring is possible.
- The limit switches on the door pillars should be checked very carefully; experts and many of those who communicate on the forums say that this is where problems often occur. There may simply be a bad contact that needs to be adjusted.

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;
- Individual light lamps;
- Instrument lighting on the control panel;
- Light in the glove compartment, cigarette lighter and separate bulbs for some buttons and switches.
The general light in the VAZ 2114 is located in the car interior and illuminates it. The engineers decided that it would be optimal to place it above the heads of the driver and front passenger, so it is simply built into the headliner and bolted there. Usually this lamp lights up when one of the doors is open, and goes out when it is closed. This is familiar to us from the classics, where a similar system was organized with light bulbs on the door pillars.
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.

Greetings to all ! Tell me too. The light in the cabin, the fisheye and the trunk light do not work. The tidy is all in order. The door switches are in good working order. Pres and relays are intact. Tell me where to dig? Where to start searching? Auto VAZ 2115
move the chip as described below, it won’t help, remove the mounting block... oxidation.
My friend’s interior lamps did not work and, accordingly, the polite lighting did not work. We dug through everything. The reason was in the fuse box. When it was removed, everything was oxidized to the point of horror. We cleaned the block and everything worked.
I’ll try to take pictures, without light it’s not very good
Since the front is intact and the connector is in place, then most likely the track in the MB has burned out
move the sh9 connector in the mounting block under the panel, everything else works, the tidy for example?
Yes, the whole panel, Bordacek, the light in the trunk, it all works
The light in the trunk is powered by the dimensions, that's why it's on
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.
Useful video
You can glean additional interesting information from the video below:
The electrical equipment system of the VAZ 2114 car includes a whole range of different lighting devices.
It's good when it's light in the cabin
Conventionally, they can be divided into the following groups:
- Headlight;
- Tail lights;
- Lighting in the cabin.
To make it easier for the driver to navigate the road at night, halogen low and high beam lamps are installed in front of the car in the headlight unit. Turn signal lamps are also installed in one unit with them, so that when repairing the car the entire unit can be removed. At the rear there is one block on each side, which includes brake lights, turn lamps and reverse lamps.
The purpose of each of the fuses on the car
If you turn over the removed cover, then on its inside you will see a diagram of the location of the relays and fuses in the mounting block (fuse block). On it, all these elements are numbered and designated from F1 to F20. Naturally, everyone is responsible for the performance of various consumers in the vehicle’s electrical network:
Diagram with the location of fuses VAZ 2114
- F1 – rear fog light and indicator lamp for turning on the latter (10 A);
- F2 – turn signal breaker relay, VAZ 2114 emergency alarm, turn signals (10 A);
- F3 – front and central interior lighting, trunk, trip computer and brake light bulbs (7.5 A);
- F4 – heated rear window (20 A);
- F5 – sound signal, cooling system fan (20 A);
- F6 – power windows (30 A);
- F7 – electric motor for heater, front window, washer, glove compartment lamp, cigarette lighter (30 A);
- F8, F9 – fog lights, right and left, respectively (7.5 A);
- F10, F11 – left clearance, as well as right, indicator for turning on dimensions, license plate lighting, as well as instrument lighting lamp, ashtrays (7.5 A);
- F12, F13 – right and left low beam, respectively (7.5 A);
- F14, F15 – high beam left and right, respectively (7.5 A);
- F16 – turn signals, dashboard indicators – parking brake, low battery, etc., as well as a trip computer (15 A);
- F17-20 – reserve respectively for 7.5, 10, 30 and 20 A.
The VAZ 2114 fuse diagram also contains backup fuses for 7.5, 10, 20, and 30 A, located in the lower part of the VAZ 2114 fuse block. Having pulled out the supposedly blown one, you should inspect it visually. If it is clear that the integrity of the thread is broken, then it can be unequivocally stated that the reason for the inoperability of the vehicle equipment lies precisely in the malfunction of the fuses. You can replace the inoperative one with a backup one of the same power according to the data that is presented to you by the diagram on the back of the plastic cover of the mounting block.
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.
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.
Basic lighting
In a standard way, on the base model the issue of interior lighting on this car is resolved quite simply:
- interior lamp of VAZ 2114;
- individual interior lighting lamp;
- dashboard lighting.
There is also lighting for the glove box and interior lighting of the VAZ 2114, which includes illumination lamps for the front ashtray, heater switches and levers, and the hydraulic corrector scale for the front lamps.
The interior lighting is a simple electrical device. Built into the upholstery in the middle, upper part of the body, above the heads of the driver and passengers. It should light up when the doors are opened and go out when they are closed, a simple electrical signal is supplied from limit switches installed on the door pillars. The interior has switches on the front and rear side pillars on each side for manually turning on the dome light.
What kind of light bulbs are there?
In the VAZ 2114 car, two lamps are responsible for interior lighting. One of them, also called the navigation one, is responsible for individual lighting and is located in the front part of the ceiling between the sun visors.

Both bulbs are ordinary incandescent.
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.
