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.
Contacts
Any detachable connection by default is a weak point in the electrical circuit.
Therefore, immediately after the fuses, you should check the condition of the contacts, because their malfunction can also be the reason why the devices discussed in the article do not work in your VAZ. In domestic cars, the terminals of the fuse socket or connecting blocks often fail. If they are poorly connected or contaminated, the contact resistance increases and, accordingly, the metal elements heat up. This effect provokes the melting of the plastic, which, in turn, flows between the contacts and creates an insulating layer.
To find such a malfunction, it is enough to inspect the pads, starting with the safety ones and ending with those that go to the devices. It is very difficult not to notice traces of burning. Similarly, oxidation and simply poor contact contacts worsen conductivity. In the first case, the metal elements of the terminals must be cleaned with a regular school rubber band, and in the second case, the clamps must be adjusted.
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.
Additional Tips
The cigarette lighter socket in the VAZ-2115, as well as 14, 09 and other models is designed to power the following household appliances:
- phone charger;
- tablet or laptop;
- pump for car wheels;
- car vacuum cleaner and other household appliances with a special connector and the ability to be powered from a 12 V network.
When such devices are turned on for a long period of time or when moving, the contacts overheat and burn. Frequent use of the cigarette lighter socket leads to its rapid failure and can cause the fuse common with the radio to blow out.
If, after replacing fuse element F4, the functionality of the radio is not restored, the cause may be a blown starter fuse.
Replacing this insert (No. 14) sometimes quickly solves the problem. To prevent the starter safety insert from burning out, when performing work using the cigarette lighter while parked (for example, inflating a tire, cleaning the interior) or listening to the radio, you need to start the car to idle.
You cannot replace blown fuses with bugs. Homemade inserts are unable to melt in time in the event of a malfunction in the electrical circuit or devices. This may cause the wiring to catch fire.
When repairing contacts, it is not recommended to twist the wires. This method causes local heating of the contact and can also lead to a fire. In automotive circuits, you need to solder all contacts well or use special fastening connectors.
- Basic fuse faults
- Bad contacts
- Broken wiring
- Short circuit
- Bulb burnout
- Repair
Some components that belong to the electrical system are interconnected, so drivers often have complaints that the cigarette lighter and radio in the VAZ-2114 car do not work at the same time ✔. Often the cause of a malfunction is the connection of devices whose power exceeds the permitted value.
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.
The relationship between a car lighter and a radio in VAZ cars
A common problem for all VAZ car models (2114,2115, 2109, 2110, 21099), this is the same voltage supply circuit to the car player, with output to one common fuse, which is additionally responsible for the power supply:
- cabin heater (stove);
- cigarette lighter;
- heated rear window;
- the radio itself.
Thus, a failure as a result of a break, short circuit, etc., in the electrical circuit of any device leads to the shutdown of the rest.
Since the tape recorder is equipped with an additional safety device, coming after the main one, after checking them and replacing them, if necessary, the operation of the head unit, like all the above-mentioned equipment, is restored. If only the cigarette lighter (without the player) resumes operation, the cause of the malfunction should be sought in the car radio itself (which is the topic of a separate article).

The price of a complete power supply starts from 2300 rubles, melting elements from 100 rubles, a set from 400 - 550 rubles.
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.
Car socket for electrical appliances
If we pull the insert out of the socket, we get a real 12 V car socket. Naturally, in order to be able to receive electricity from it, we will need a special cylindrical plug. All automotive electrical appliances listed above are equipped with these plugs. Typically they have one central positive contact and two side (negative) contacts. Most plugs, in order to further protect electrical appliances from overloads, are equipped with fuses that are located inside them.
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.
Wires
Broken wiring is a very common problem in domestic cars. Often it is impossible to determine by eye where exactly the malfunction has occurred, and therefore a multimeter should be used.
Testing starts from the fuse if the radio or cigarette lighter fails at the same time, and from one of the devices when it is the only one that does not work.
Once a faulty core is discovered, it must be replaced immediately - we do not recommend twisting it or wrapping it with electrical tape. As noted above, any connection becomes a weak point in the chain.
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.

Methods for solving the problem
Now that the main causes have been sorted out, you can move directly to elimination methods.
It is worth warning that if the motorist does not understand the design or is not sure that he can repair the fault on his own, then it is recommended to turn to a professional car service center.
So, let's look at what ways to deal with the malfunction.
Fuse
Disassembled dashboard while searching for fuse and cigarette lighter faults.
The most common cause of malfunction or inoperability of the electrical circuit of individual elements is the notorious fuse.
This is where you need to look for the cause first.
The fuse box socket – F4 – is responsible for the radio and cigarette lighter. The fuse marking in it should be 20A.
But it does not always withstand the load placed on it. Thus, frequent and large use of additional devices can lead to frequent burnout of this element. Therefore, to check it is worth removing and inspecting the fuse itself. If necessary, the element is replaced with new ones and if everything works, then the reason has been found. But if the problem does not go away, then you should look for it in other places.
Contacts
Checking the contact group of fuses for malfunction
A contact group is another common cause of a non-functioning electrical circuit. In most VAZs, the connecting contacts of the fuse with the block or in the circuit of the wire block oxidize or burn out, and molten plastic can interrupt the contacts.
To troubleshoot the problem, you need to check all the contact blocks of the wires that go from the radio and cigarette lighter to the fuse box. So, it is oxidation and insufficient contact that can lead to the inoperability of the elements.
Wiring
Another reason could be broken power wires. So, in order to find and fix the fault, you will need a tester that will test the wiring and find a broken wire . It is recommended not to fasten the wire using the old “old-fashioned method” using electrical tape, but to replace it with a new one. This will take little time, so it’s better to do everything in such a way that you get a short circuit and cause big problems.
Short circuit
Location of frequent failure of the cigarette lighter socket.
The worst thing that can happen is a short circuit. The reason for this phenomenon is that frequent use of the cigarette lighter loosens the socket and this can lead to the contacts crossing and causing a short circuit.
The standard cigarette lighter is just a disaster for the VAZ-2114.
Here, the treatment for the malfunction is quite simple - replacing the socket. But, often motorists take a low-quality and cheap product, which repeats the procedure after a short time.
