All electric interior lighting can be divided into the following components:
- dashboard lighting (we have already talked about it, as well as its malfunctions, earlier, so today we will not dwell on it in detail);
- main interior lamp of VAZ 2114;
- lamps for individual lighting;
- illumination of glove compartments and cigarette lighter.
The most important and basic light source of all the elements listed above is the VAZ 2114 lamp. It is mounted on the ceiling of the passenger compartment in the front part and is turned on using limit switches located in all doors of the car. When you open even one door, the light instantly lights up, and when all doors are closed, it turns off.
In addition, it is also possible to force the lamp to be turned on/off using special buttons located on the side pillars.
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
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.

Tuning the ceiling
Such a pleasant and exciting thing for a car enthusiast as tuning with your own hands is also possible with a ceiling lamp for interior lighting. Instead of the usual one, a ceiling 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 gradual switching off of the lamp;
- Automatic shutdown when the door is not closed or closed incorrectly after 30 minutes.
The price for such a ceiling is only about five hundred rubles, so the choice is obvious. The procedure for installing and connecting a ceiling with a programmable LED lamp:
- the plastic diffuser of the standard ceiling is removed;
- the wires are disconnected from the contacts of this device;
- Unscrew the four screws holding the light housing to the ceiling of the housing and remove the body of the old device;
- LED illuminator is released from a transparent plastic diffuser cover;
- the wiring is connected to the terminals of the LED illuminator according to the diagram;
- the housing of the new ceiling is fixed to the ceiling of the housing in the standard position with self-tapping screws;
- a plastic diffuser is attached to the body.
It should be noted that such a lighting device emits a brighter light, which in the dark is a good helper for all people in the car.
Lighting in the VAZ-2115 is one of the most important components of comfortable movement in a 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 object in the glove box, so the driver should make sure in advance that all light bulbs and other electrical components of the car are working stably and reliably. But what to do in a situation where the lighting fixtures in the interior of a VAZ-2115 for some reason refuse to fulfill their duties?
Fuse
There are fuses in the lighting circuit. The lamp is activated and voltage is supplied to the lighting lamp only if the fuse is working properly. In different years of model production, two different types of mounting blocks were installed on the car from the factory. Note the location of the dome light fuse on each of them. First, let's look at the location of the fuse in the mounting block of the new model. This element is also responsible for the operation of the brake light.
The power of the interior pre-illumination is 7.5 Amps. To quickly replace a blown element, it is recommended to carry with you a spare set of fuses of all capacities.
In the old-style mounting block, this element is located a little differently - it comes 7th from left to right . The power of the element in this version of the block is 10 Amperes. In addition to interior lighting, a circuit to the brake light goes through this element. This may help when trying to diagnose a malfunctioning ceiling light.
If, after replacing a burnt-out part, the light in the interior of the VAZ 2114 does not come on, you should look for the reason in the wiring and the light bulb.
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:
- Bulb.
- Ceiling lamp.
- Fuse.
- Wiring.
