The VAZ-2115 car is a fairly popular vehicle, the brainchild of the domestic automobile industry. Therefore, on the Internet you can often find questions from the owners of this car regarding the incorrect operation of the cigarette lighter.
The fact is that in the modern world, in most cases, the cigarette lighter is not used at all for its intended purpose. Most often, various gadgets are charged with its help. Simply put, the cigarette lighter is now used as a power source in the car. Unfortunately, it often happens that the device stops working. There are quite a lot of reasons for this. But first of all you need to check the fuse.
Many people believe that if the lighting of the cigarette lighter socket works, then the fuse is intact. But in fact, the backlight is powered by a completely different device. It follows that regardless of whether the backlight is on, the cigarette lighter fuse on the VAZ-2115 should be checked first.
How to replace the cigarette lighter fuse on a VAZ-2115
In order to replace a cigarette lighter fuse that has blown, or to check its functionality, you should open the cover of the mounting block.
By the way, there are special symbols on it, by looking at which you can easily determine the fuse you need. But there is a small problem. The fact is that there is no fuse symbol on this diagram. In this regard, the driver or technician entrusted with the repair will need to find a diagram of the location of the fuses in the mounting block.
It is then that it will become clear that this electrical circuit is protected by fuse F7 (30A).
But it also happens that when examining the F7(30A) it becomes clear that it is working. In this case, you need to check one more fuse - F4 (20A). It is he who will most likely be burned out.
Why the cigarette lighter on a VAZ-2114 does not work: we are looking for a problem in the connectors and wiring
If all your efforts do not bring the desired result, check the connectors and wiring integrity. First of all, pay attention to how the “positive” wire and the “ground” wire are connected to the device glass. Remove the protective insulation from the contacts and inspect the connections. Restore them if necessary. After this, check the contacts of block X1 on the mounting block. The cigarette lighter power wires fit exactly to it. Unfasten it from the unit connector and inspect the contacts. If they show signs of oxidation, clean them and treat them with an anti-rust liquid (such as WD-40). Next, you should ring the wires going from the block to the cigarette lighter glass. They can be identified by color. If you find a broken wire, replace it locally, or better yet, replace the entire harness.
Replacing the cigarette lighter
If both fuses are good, most likely the cigarette lighter itself will have to be replaced.
You can do this either independently or by contacting service centers. But our people are not used to paying money for something that they can easily do with their own hands. Therefore, there are many manuals on the Internet that tell you how to independently replace the cigarette lighter on a VAZ-2115. All you need to replace the device yourself is, of course, a new cigarette lighter and a screwdriver. Then they proceed according to the following scheme:
- The “–” terminal wire on the battery is disconnected.
- On the left trim of the center console of the instrument panel, you need to unscrew all the screws.
- Remove the trim.
- The wiring harness connector must be disconnected from the cigarette lighter.
- Pull out the lamp illuminating the ashtray, together with the wiring harness block and socket.
- Push the cigarette lighter out, despite the resistance provided by the latches.
- Remove the fuse from the center console.
- Remove the fuse holder and the backlight from the housing.
- Remove the cigarette lighter lamp from the socket.
- Remove the cigarette lighter lamp socket guide.
- Take a new cigarette lighter and install it in reverse order.
As you can see, even a beginner can independently replace the cigarette lighter on a VAZ-2115. However, if you are not confident in your abilities, it is best to turn to professionals.
How to remove the cigarette lighter
Sometimes the cause of the breakdown is not the fuse. In this case, repairs are performed. To remove the cigarette lighter, perform the following steps:
- Turn off the engine and open the engine compartment. Disconnect the negative terminal from the battery. This prevents burnout of on-board network elements during repair work.
- Remove the protective pad located to the right of the driver’s foot. To do this, unscrew the screws.
- Disconnect the cigarette lighter plug. Remove the lighting fixture with the socket.
- The metal clips are pulled out. This will make it easier to remove the device.
- Remove the metal cylinder.
VAZ 2115 fuses: where they are, replacement
The location of the mounting fuse block in the Lada Samara family car is different from previous modifications.
Where is it located: the main board is installed in the engine compartment, the additional module is in the central channel on the right.
The process of replacing fuses (hereinafter referred to as modules) is not at all complicated, similar to the VAZ 2110, 2112, but it requires attentiveness on the part of the technician. Violation of the installation technology, incorrect selection of the module leads to its overheating and short circuit.
If you encounter difficulties with replacement, contact a specialist service station.

- Short circuit in the circuit;
- Damage to insulation, oxidation of terminals, loosening of contacts;
- Water entering the mounting block, condensation formation, deformation due to high operating temperature.
COMMON MALFUNCTIONS
What to do if the alarm does not work
In the mounting block, the cooling fan fuse often blows, as well as the cigarette lighter fuse on the VAZ 2114. The cigarette lighter on this VAZ model often shorts out on its own; you can call this a factory defect. Another reason for burnout is the installation of various devices of higher power in the cigarette lighter socket, for example, a compressor for inflating tires. But before changing the fuse for the VAZ 2114 cigarette lighter, you need to check the condition of the cigarette lighter socket itself. Often a device is inserted into the socket by twisting the plug, and the cigarette lighter block begins to dangle and short out. In this case, the wire going to the cigarette lighter may fray or break, and for this reason the fuse will constantly blow.
The fuse link (20A) of the cooling fan is also loaded with an audio signal, so you can determine a blown fuse F5 by the absence of a car horn. Another fuse link, responsible for the operation of the fan, is installed in the car interior next to the engine ECU under the dashboard. Fuses can blow due to a short circuit in the fan motor - standard fans are not very reliable and often fail.
Contacts often burn out and tracks on the mounting block burn out due to a short circuit in the electrical circuit. When moisture gets on the connector pads, the contacts oxidize. The power supply unit in the VAZ 2114 model is considered a rather weak element and requires repair or replacement. It should be noted that the mounting block 2114 is quite problematic to repair, so if a malfunction occurs in it, you should think about replacing it. The cost of a power supply unit for a front-wheel drive VAZ ranges from 2 thousand to 3 thousand rubles. But it’s better to replace a burnt-out unit than to go through the hassle of restoring it.
Often the central locking on VAZ 2113-2114-2115 cars refuses to work normally, and many drivers cannot determine the cause of the malfunction. The thing is that the central locking fuse is very cleverly installed in the electrical circuit of the car. In the area of the steering column on the wires there are two fuses in a holder, one of them responds to the activation of the central locking (15A). The contact in this clip oxidizes and the central locking system does not work. If an old-style cylindrical fuse-link is installed there, it is better to immediately change it to a new type of flat one.
Keep the mounting block clean, always close the protective cover!
During the operation of a VAZ 2114 car, a situation may arise when the cigarette lighter, windshield washers, fan and other elements of the electrical system stop functioning. In such a situation, the problem should be looked for first not in the devices, but in the fuses of the VAZ-2114 car. Most often, the device stops working because the fuses have blown. This also applies to the cigarette lighter.
Initially, the cigarette lighter was conceived exclusively for smokers, but today this element has a broader purpose. Cigarette lighters are used to charge phones, connect DVRs, Navigators and other devices.
If a small amount of current is required to recharge a phone or tablet, connecting more powerful devices may cause system failure. Such devices include:
compressors, car heaters; vacuum cleaners; autoboilers, etc..
Replacing fuses on a VAZ 2115
Preparatory stage:
- Driver, head at “10”;
- Flat head screwdriver;
- A set of new modules;
- Plastic pliers for removing the relay block;
- Rags, additional lighting as needed.
Sequencing:
- We turn off the engine, open the hood, remove the terminals from the battery;
- On the left side, closer to the windshield, there is a mounting block. Unscrew the two bolts around the perimeter;
- We disconnect two blocks with wires, remove the power supply assembly;
- We carry out troubleshooting and check the serviceability of all modules.
You can do this in two ways:
- Visually: checking each module for the integrity of the melting element;
- Using a multimeter: measuring the resistance at the end switches of the module without dismantling it.
Each method is applicable and effective.
After replacing the faulty fuses, we assemble the structure in the reverse order.
Some motorists practice the second method: without dismantling the mounting block. We remove the fuses one by one, check them for integrity, and replace them with new ones as necessary.
If you notice that a unit in your car has suddenly stopped working, do not rush to dismantle it and replace it with a new one. First of all, inspect the mounting block, check the modules for integrity. Most likely some kind of fuse has blown.
Only after replacing the module does not help eliminate the problem, proceed to diagnosing the equipment and checking the integrity of the electrical supply circuit.
VAZ 2114 cigarette lighter fuse: location, breakdowns and their elimination
Sometimes motorists are faced with the fact that the cigarette lighter on a VAZ 2114 does not work. This seemingly minor problem can lead to very big difficulties on the road. Indeed, nowadays a car cigarette lighter not only serves its intended purpose, but is also used to connect various chargers (for example, for smartphones) and to power some electronic devices directly (for example, navigators). That is why it is so important to understand the electronic circuit of the cigarette lighter and be able to repair it in a timely manner. We'll talk about how to do this today.
Recommendations for care and maintenance
- Buy original fuses. Domestic or foreign, it doesn’t matter;
- Install strictly in accordance with amperage ratings. Unacceptable with lower or higher current strength. In the first case, this will lead to damage to the module, in the second - to breakdown of the unit, which is attached to the fuse;
- Carefully check the quality of fixation of terminals and limit switches on the board. If loose, tighten and press with pliers. A spark can cause a fire and melting occurs;
- If moisture gets in or condensation forms inside the mounting block, remove the cover, dry it, and if necessary, blow it with a stream of compressed air.
Carry out preventive and diagnostic work in the fuse box with the battery terminals removed in order to prevent a short circuit in the circuit.
The average service life of fuses is 40 – 60 thousand km. The service life of foreign analogues is 10–15% longer. Before replacing, read the instructions and get advice from service station specialists.

Analysis of the operation of interior electrical appliances
On the VAZ 2114, as on other cars, the cigarette lighter is one of the weak points in the operation of the entire interior electrical network, for which there are a number of reasons.
The first is the demand for this device - anything can be connected to it, from a gadget charger to a vacuum cleaner. The problem becomes even more urgent if we consider that splitters are often connected to the cigarette lighter with the parallel use of several current consumers.
The second reason lies in the mechanical unreliability of this unit, which over time becomes loose due to loads and shaking, losing the tightness of the connection.
Often the cigarette lighter and radio of the VAZ 2114 do not work due to the connection of devices to the connector that exceed its rated power values.
To understand why both options failed at once, you need to read the car’s instructions, which will indicate that not only the audio system and the cigarette lighter, but also the interior heater and heated rear window are connected to the same power circuit with a common fuse.
Consequently, an open circuit, short circuit or other breakdown of one of the devices can lead to the failure of others in the network.
As a rule, replacing this fuse is enough to restore the function of all the listed devices, but if everything works, except for the tape recorder, you need to pay attention to the additional fuse of the VAZ 2114 radio, which is responsible for a separate audio device.
