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.
Possible causes of malfunction
The most common reason why an electric lighter and a record player stop working at the same time is a blown fuse. The fuse link in VAZs of these models is common for the circuits of the car player, rear window heater, interior heater and electric lighter. If a short circuit or malfunction occurs in each of these devices, the insert is destroyed and all listed circuits are switched off.
The reasons why the cigarette lighter and radio fuse fails are often as follows:
- destruction of the fuse element due to a short circuit or malfunction of devices connected through it;
- contact failure in the safety panel (due to shaking, mechanical impact, etc.);
- oxidation or burnout of contacts due to frequent power surges in the network;
- burnout of the cigarette lighter lamp;
- loose contact or burnt out spiral.
To determine the malfunction, you need to visually inspect and check with a tester the fuse-link and the devices whose circuits it disconnects.
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.
Causes of car cigarette lighter malfunction
Returning to our main topic, namely, why the cigarette lighter and radio do not work on the 2114 and other models, we list the possible causes of malfunctions:
- the safety device has burnt out;
- contact is broken in the fuse block;
- contacts have oxidized or burned due to frequent voltage surges during operation;
- the backlight burnt out;
- short circuit.
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.
Basic fuse faults
Fuses in cars play an essential role, protecting electrical appliances from power surges and short circuits. They take on the impact of such factors and maintain the working condition of the electrical appliance, while burning out themselves. But if this happens regularly, you need to check the fuse box and determine the cause of the breakdown.
Bad contacts
One of the most common reasons for a situation where a fuse does not work is related to the contact group. With frequent voltage surges in most VAZ cars, contacts burn out and plastic melts, which can interrupt the contact of parts. A similar condition is also observed when the contacts have oxidized and become coated.
Broken wiring
When operating a car, malfunctions such as broken wires often occur. To determine for yourself where the accident occurred, you will need a special device (multimeter, tester) with which to check the working condition of the contacts. To find an open circuit, the device is set to ohmmeter mode, and the leads are connected to the circuit being tested. In the place where the wiring is broken, there is high resistance.

Short circuit
A short circuit occurs when the contacts in the block are strongly oxidized and crossed due to frequent use of the cigarette lighter socket. This condition is indicated by a fuse blowing shortly after replacing it. To determine the short circuit zone, you need:
- Inspect the entire area for damage.
- Disconnect the section being tested from the main wiring.
- Use a multimeter to set the dialing mode.
If there is a short circuit in the area being tested, the device beeps.
Bulb burnout
The contacts of the light bulb are in a common electrical circuit, so when it burns out, the cigarette lighter and radio on the VAZ also stop working. The reason for their burnout may be high voltage, breaks or short circuits in the wiring, water or poor fastening.

Additional power relay modules are installed in the central channel, under the dashboard. To get to the parts, first remove the plastic cover.
- Gasoline pump;
- Radiator fan.
Common causes of fuse failures
- Natural factor - due to long-term operation of the technical device;
- Mechanical damage, accident, impact, collision;
- 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.
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.
What is the Samara cigarette lighter of the fourteenth model
The design of the cigarette lighter for the VAZ-2114 is the same as for other cars. It consists of a glass (socket) and an insert. The socket is a metal cylinder, the walls of which are connected to the “ground” of the car. It is also equipped with a central terminal connected to the “plus” of the on-board circuit.
The main element of the insert is a nichrome spiral. It is enclosed in a metal case with a plastic button-handle. The insert is located inside the glass. In the off position, its body is in contact only with ground. When you press the button, the insert goes deeper into the glass, where one of the spiral contacts comes into contact with its central terminal, completing the circuit. It is held in the socket thanks to two special bimetallic “ears”. The current passing inside the coil heats it red hot. Thanks to this, we actually have the opportunity to light a cigarette.
The device turns off automatically. When the glass is heated to a certain temperature, the “ears” unclench and release the insert. At the same time, a characteristic click is heard, notifying the driver that the device has turned off and is ready for use.
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.

Trouble-shooting
Having established the reason why the VAZ cigarette lighter and radio are not working, we correct the detected breakdown. The list is given in accordance with the listed faults.
- We remove the fuse box (the hatch on the left side of the steering column of the car). We remove the device marked F4 (20 ampere fuse), test it for serviceability with a simple screwdriver probe, if this moment is not visually determined. And we replace it with a new one from the mandatory kit for such cases.
- Check the conductivity of the contacts with a probe. If they are loose, tighten them.
- Strip or resolder the contacts, depending on the situation.
Paradoxically, a burnt-out light bulb breaks the contact circuit (a kind of fuse). Replace it with a working one of the same power.
A short circuit most often occurs due to a loose cigarette lighter socket and a malfunction of its heating coil. If you have the opportunity, then replace them with new ones or restore them to proper condition.
Expert advice
Professional automotive electrical repair technicians complain that even when carrying out repairs that are so insignificant in scope and complexity on their own. Some car owners manage to violate basic rules, thereby significantly aggravating the problem and transferring it to another, more complex (and expensive) repair category.
It is for this reason that we provide several recommendations for replacing and repairing car cigarette lighters.
No replacing fuses with improvised means (despite the advice of so-called experienced drivers). A single case of such a replacement cannot serve as a reason for its re-use.
A definite no to any direct connections (twists). All work must be done using a soldering iron.
When purchasing a new cigarette lighter from an unknown retail outlet, if possible, check its serviceability and quality, using a tester and visually.
Before working on any electrical appliance, be sure to de-energize the vehicle's electrical system. Otherwise, in addition to shorting, you expose yourself to the risk of electric shock.
Do not neglect to carefully study the instructions and any available information.
Don't be overly confident. If you doubt your capabilities, seek help from professionals.
Do not think that this problem is typical only for VAZ 2114 (2115, 2109, 2110, 21099) cars. The same malfunctions with some (minor) differences are often found in imported passenger cars. As an example, we can cite the Daewoo Matiz, Renault Logan, Toyota Corolla and a number of other models of various brands.
The reason that the cigarette lighter and radio does not work on the VAZ-2114 is the imperfection of the car’s electrical circuit. Problems similar to this also arise in the VAZ-2109, -15, -099 and -10 models.
