Cigarette lighter fuse for VAZ 2115 – where to find it, how to change it

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.

Typical faults

Where to look for the reason if the VAZ 2114 cigarette lighter does not work? It is necessary to take into account that the failure of the AP, as well as the sockets directly for connecting it, are two different things. Moreover, the AP is not used as often as a socket, since this socket is often used to connect various electronic devices. The device may stop working when using low-quality chargers for equipment made in China. Especially when it comes to using an AP splitter, this can, in principle, cause its breakdown (the author of the video is the Expert R channel).

The AP circuit is designed to power various gadgets, but its maximum load capacity is 20 Amps. The corresponding 20 A fuse element is located in the block and is marked with the symbols F4. If you use a splitter, the load on the circuit will be simply catastrophic and over time the fuse will fail, but this is not so bad. It is much worse if the wiring fails, since this can cause not only a short circuit, but also a fire.

It often happens that if the cigarette lighter stops working, the radio does not work. In this case, the problem most likely lies in the circuit or functionality of the safety element. The radio can be connected directly to the battery or to the AC cable, so you shouldn’t be surprised at its inoperability if the latter breaks down.

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:

1. The “–” terminal wire on the battery is disconnected.
2. On the left trim of the center console of the instrument panel, you need to unscrew all the screws.
3. Remove the trim.
4. The wiring harness connector must be disconnected from the cigarette lighter.
5. Pull out the lamp illuminating the ashtray, together with the wiring harness block and socket.
6. Push the cigarette lighter out, despite the resistance provided by the latches.
7. Remove the fuse from the center console.
8. Remove the fuse holder and the backlight from the housing.
9. Remove the cigarette lighter lamp from the socket.
10. Remove the cigarette lighter lamp socket guide.
11. 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.

Car cigarette lighter

The socket of this device can be used to connect non-standard equipment:

• phone chargers;
• laptops (tablets);
• compressors;
• vacuum cleaners;
• and so on.

In general, any household appliance that has a special adapter for connecting to the cigarette lighter socket.

The main disadvantage of this gadget is its unreliability in providing a long-term electrical connection. And also, switching high currents. The design features of the socket and the car cigarette lighter itself do not allow them to be kept in close contact with each other. As a result, due to vibrations of the car while driving, frequent disconnection (connection) of contacts occurs. Which leads to sparking of connections and in some cases can cause a short circuit. The same applies to adapter devices for connecting auxiliary household appliances.

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.

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:

1. 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.
2. Remove the protective pad located to the right of the driver’s foot. To do this, unscrew the screws.
3. Disconnect the cigarette lighter plug. Remove the lighting fixture with the socket.
4. The metal clips are pulled out. This will make it easier to remove the device.
5. Remove the metal cylinder.

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.

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.

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.

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 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.

How to use a cigarette lighter so that it works for a long time

If you use your cigarette lighter correctly, you will maintain its usability for a long time.

First of all, you should not connect to it powerful consumers such as a compressor, which many now use to inflate wheels or blow air into the power unit. It is more correct to power this device through a rechargeable battery.

In this way, you will protect the wiring and fuses from overloads, and, therefore, they will not overheat, burn out or melt. Some craftsmen install a separate socket in the car for such devices - this is very forward-thinking and effective.

Also try not to stick adapters into the VAZ socket if it turns out that they are too thick - this will quickly break the core, which is made of ceramic.

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.
