If in the past the cigarette lighter was used for its intended purpose, now it has become a kind of 12V socket, and its functions include connecting various electrical gadgets, such as a fan, a vacuum cleaner and chargers for them. Therefore, failure is a big problem for the car owner and requires an immediate solution.
You can learn how to replace and repair a VAZ 2107 cigarette lighter, as well as its structure and diagram, from this article.
According to the original idea, the car cigarette lighter was used so that the driver could light a cigarette from it instead of matches at any convenient time. Over the rather long period of operation of this device, its structure has not changed, and it can be found in any model of the domestic automobile industry, including the very first ones.
↑ Cigarette lighter device
Its device itself consists of two main parts: a cartridge and a socket and includes a small number of components:
- The handle is made of plastic, shaped like a button.
- The metal rod is located in the center of the socket. It functions as the positive pole.
- The metal body of the cartridge acts as a negative pole.
- The insulator located between the body and the rod eliminates the possibility of their contact.
- Nichrome spiral. Used as a heating element and also provides a plus and minus connection.
↑ The principle of operation of the cigarette lighter
It is possible to heat up to a sufficiently high temperature by the current that approaches the heating part. As soon as the coil reaches a certain temperature, the current supply is stopped due to a thermal relay.
The device itself and its socket are located in a convenient place for the driver - on the dashboard. This place is designed from the outside as a recess with a metal frill. Inside there is a central contact that receives the positive from the battery.
When the panel is turned on, the built-in light is turned on.
In order to start the heating mode, you need to press the handle, thanks to which the cartridge is immersed in its place and fixed there with bimetallic plates.
Next, the positive contact of the cartridge is combined with the positive contact of the socket, the same goes with the negative terminal of the socket and the negative terminal of the cartridge.
Afterwards, the spiral heats up due to the current flowing through it and reaches the required temperature in 15-20 seconds. A specific click is a sign that the bimetallic plates have separated due to increased temperature and the cartridge has taken its standard place.
↑ New ways to use the cigarette lighter
With the advent of modern technologies, the functionality of such a simple thing as a cigarette lighter has changed and become much more diverse than usual. Now it is increasingly being used as a socket for a variety of electrical devices. However, you can only use those devices that do not require more than 12V for power. Therefore, developers began to produce a wide range of such devices for the car. In addition to the above, these include:
- heater;
- seat heating;
- devices for interior lighting and so on.
Such special devices provide an input for connecting to the cigarette lighter. There are also splitters on sale that can be used to connect several devices at the same time.

The cigarette lighter uses three wires to operate:
- "minus" mass;
- “plus”, carried out through the battery fuse;
- “plus” is in operation only when external lights are used, as it is connected to the instrument illumination lamp from the side lights.
Protection against various ignitions and overheating is also provided, so the battery is equipped with a fuse. The possibility of the cartridge jamming in the socket is excluded.
Typically, such fuses are made in the form of a low-fusible metal washer, which melts at an excessively high temperature and cuts off power to the battery, causing the cigarette lighter to become de-energized.
Also, some of these devices have a fuse built into the socket. Its difference lies in the simple replacement when the washer melts.
But recently, bimetallic fuses have been used quite often and are used many times. It is many times more profitable than other types because not only prevents the fuse from blowing, but after some time the contacts can open again.
Help with choosing a part
Today, there are many options for the VAZ 2107 cigarette lighter available on the market. The average price of a part is 200 - 400 rubles for a standard element and 500 - 600 for a European cigarette lighter. It is advisable to choose the latter option. It has several advantages relative to the classic part.
- Reliable fixation. The European cigarette lighter is securely held in the socket, and the fixing nut does not unscrew.
- The appearance and backlight are prettier.
- A modern car lighter allows you to connect several devices at the same time.
↑ The cigarette lighter does not work. What is the reason and what to do?
Please note that rechargeable devices are not durable and reliable, they cannot last for a long time and tend to break down. You can only improve the fixation by increasing the pressure of the presser feet.
The structure of the device itself is simple: it consists only of a central contact and two presser feet. The location of the central contact is always different and can be either deep or close. And the reason for poor contact is that over time the connection between the plug and the socket becomes worse and worse, this leads to sparks and then a short circuit.
↑ Possible cigarette lighter malfunctions: signs and causes
↑ The plug does not lock into the socket or there are problems with fixation
The reason is the antennae, which tend to wear out over time and can no longer hold the cartridge.
The solution to this problem is quite unsafe, since the car owner in this case has to manually hold the head in the socket until it is completely warmed up. But there is another, more reliable and effective solution - to bend the cigarette lighter antennae.
↑ The spiral burned out while in the cartridge
The simplest solution is to change the cigarette lighter head. But you can also renew the old coil if you clean it of any soot that has formed.
According to the theory, in twenty seconds the connected coil will reach the desired temperature until it turns red and the head will pop out. If this happens in more or less time, you can adjust this time by bending or straightening the contacts.
If all of the above methods do not help, the only option is to completely replace the head.
↑ Fuse blown
In most cases, the blame for this falls on the owner of the car because... this happens when connecting several more devices using a splitter. Due to this, a lot of pressure is exerted on the cigarette lighter due to the load, which clearly exceeds the intended one. In such cases, be sure to not use the nest for too long. But the driver ignored this rule, which led to the breakdown.
A standard fuse is designed for a load of 10A; you should not use parts with a larger rating because this leads to complete combustion of the battery socket.
↑ Wiring break
Such problems are unlikely to be the fault of the driver, since they occur during use and are a common result of long use, during which they can become pinched or worn out. All this leads to loss of electrical communication.
This problem can be solved by replacing the damaged section of wiring. After replacement, it is imperative to create high-quality insulation for them so that ignition does not occur in the future. A multimeter will help you find this break.
Causes of malfunction
- It often happens that the VAZ 2107 cigarette lighter socket is a socket, as described above. The calculation scheme is simple: by multiplying the maximum current for which the fuse is designed (10 A) by the voltage of the on-board circuit (voltage 12 V), we get 120 W. If this is not just a socket, but a splitter, you need to remember this. The fuse will burn like a match (at best), and repairs will become commonplace. A load of no more than 100 W works well.
- Sometimes the contacts of the cigarette lighter itself or its connector become oxidized. Then they are cleaned, having first reset the ground to avoid a short circuit. Replacement is not necessary at all; anyone can do the repair themselves.
- The next possible failure is that many additional devices do not fit tightly into the cigarette lighter socket, contact with the walls is poor, a “chatter” begins, and a short circuit occurs. After this, the contacts melt and the cigarette lighter does not work. If the contacts are melted, repairs can be made by cleaning and re-soldering them, or replacement is required. In this case, large peak loads occur on the fuse.
- Finally, sometimes the coil on the cigarette lighter itself may simply burn out. In this case, you just need to replace the head with a new one. If you can’t find a spare part, you can carry out a simple repair - clean the cigarette lighter coil from soot and carbon deposits.
According to the rules, the spiral on the VAZ 2107 cigarette lighter should heat up red-hot and snap out within 20 seconds. If the time differs in one direction or another, the timing scheme can be adjusted by bending or bending the cigarette lighter contacts. If the adjustment does not help, then replacing the part will help solve the problem.
↑ Repair and replacement of the cigarette lighter on the VAZ-2107
Repairing the cigarette lighter, just like replacing it on a VAZ 2107, is identical to other domestic models due to the similarity in details, so the method can be used not only on this car.
First you need to figure out what tools you will need:
- screwdrivers of different types;
- pliers;
- small forceps or tweezers;
- soldering iron;
- a flashlight or lamp that can be moved;
- insulating tape;
- gloves.
↑ Repair sequence
- The first step is to de-energize the vehicle. This can be done by removing the negative terminal on the battery. Next, you need to find the car fuse socket inside the car and make sure there is good access to it. To do this, you can move the driver's seat back as far as possible, since according to the standard it is located in the central part.
- Next, you need to remove the cartridge from the socket and remove all unnecessary objects and fragments using tongs, and illuminate the surface with a flashlight during the process.
- After this procedure, you need to inspect the fuse itself, which can be found in several places: under the dashboard, hood or driver's seat.
- Once you find the fuse box, you need to find the right one. Its location is indicated in the operating instructions or on the hidden part of the hood.
- When you find the part you need, check its jumper. This is a very important part, so if it burns out, replacement is required.
If changing the part does not solve the problem, use another method.
- Remove the cigarette lighter, grab the edge with pliers and gently, without applying any force, pull it out to avoid damage to the wiring.
- Inspect the item. If a tear or poor quality connection is detected, use a soldering iron and repair the wires.
- You should also carefully inspect them for abrasions, which must be isolated.
- Once you are sure that the part is working properly, return it to its place.
All this information will help you if the cigarette lighter does not work.
Features of the procedure when replacing a short European cigarette lighter
One of the problems with the classic device is weak contacts. When driving on broken roads, the seats become loose, as a result of which the retaining ring can fly off, which can lead to a short circuit. Therefore, many owners decide to buy a short Euro cigarette lighter, also suitable for the VAZ 2107.
Its installation is carried out according to the diagram.
- The disassembly procedure is similar to the previous procedures.
- The diameter of the Euro cigarette lighter socket is slightly larger. Therefore, you should bore the old hole with a file to a suitable size.
- Install the green part of the backlight.
- We mount the landing socket.
- You need to buy a standard three-pin connector at the store. The yellow wire is soldered to the yellow, the center green to the red, and the blue to the negative black.
- Next, all that remains is to assemble the device according to the reverse diagram of disassembly and check its serviceability.
