The cigarette lighter is not one of those elements whose malfunction will prevent further operation of the machine. Its breakdown does not pose any threat to the operation of the engine or other components of the car. However, without it the car becomes less comfortable.
Long gone are the days when the cigarette lighter was used for its intended purpose. Today, as a rule, it is needed not to light a cigarette, but to provide power to various electronic and electrical devices: video recorders, navigators, audio and video players, vacuum cleaners, compressors, etc.
In this article we will look at the main malfunctions due to which the cigarette lighter does not work on the VAZ-2114. In addition, we will understand their causes and try to fix the breakdown on our own.
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.
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.
What can happen to the cigarette lighter
If the cigarette lighter in your VAZ-2114 does not work, there can be only two reasons for this: either the integrity of the nichrome spiral is broken, or there is no voltage on the contacts of the glass. An ordinary car tester or a multimeter turned on in voltmeter mode will help you determine the problem.
Attach one probe of the device to the positive terminal of the glass, and bring the second to its body. The voltmeter should show battery voltage. In this case, you can simply replace the insert with the spiral, and the cigarette lighter will work like new again. But if there is no voltage on the contacts, you need to continue looking for the problem.
Recommendations for use
In order to determine whether a fuse is good or not, drivers usually practice two methods.
- The simplest one is to remove the problematic element and see if its conductive part is intact.
- The second method is a little more complicated, but is more accurate than determining by eye. To do this, you need to turn on a non-working consumer, for example, a cigarette lighter. Without removing the element itself, we check the voltage at one end and at the other. If there is voltage only at one end, then the conclusion here is clear - the fuse is blown and needs to be replaced.
If you find that your VAZ 2115 protective elements often burn out, then it is quite possible that your wiring is not in order. In such a situation, it is better to contact a service station.
- When operating a vehicle, never install so-called “bugs” or jumpers instead of electrical fuses. If the voltage in the circuit increases, the consumer may simply fail completely.
- Replace the burnt out one with a whole one of similar value.
- It would be wise to always keep in stock a set of electrical fuses of different amperages. They won’t take up much space, but in certain situations they can help out.
Electrical Fuse Kit Sorry, there are no surveys available at this time.
Where to look for a blown fuse
Has the cigarette lighter on your VAZ-2114 stopped working and there is no voltage at its contacts? Start your diagnosis by checking the fuse. To do this, you don’t have to disassemble anything, and the only tools you need are a multimeter in tester mode or a homemade tester made from a lamp and two wires. A natural question that arises in a situation when the VAZ-2114 cigarette lighter does not work: “Which fuse should be checked and where to look for it?”
In the Samara model fourteen, this protection element is located in the mounting block located in the engine compartment of the car. Open the hood and in the far right corner (looking at the windshield) you will see a black plastic box. This is the car's mounting block. The cigarette lighter fuse, depending on the modification of the car, may be designated as F4 or F7. It is designed for a maximum current of 30 A (in some modifications its rating can be 20 A).
Method No. 1
- Let's remove the terminals first (so that a small light bulb replacement doesn't turn into a big fire).
- We disassemble the torpedo in the place where the regulator is located.
- There are two lamps there, one is located directly on the regulator itself, and the second is located on the air flow control levers (hot, cold, on the legs, on the glass). It's better to check both.
- At the same time, it is possible to solve problems that arise with heating air ducts, since from the factory their nozzles are made in such a way that they do not fit tightly together, and accordingly, the operation of the stove becomes noisy and ineffective.
- We change the lamp (you can look for a diode, the service life is longer), put on the terminal and check it on the disassembled dashboard.
- If everything is fine, then we assemble it in reverse order.
Fuse diagnostics
To check the fuse, carefully remove it from its seat, connect its leads to the probes of the multimeter and “ring”. If you are using a homemade tester made from a lamp and wires, connect the element being tested to the gap in one of the conductors. Connect the wires to the battery terminals. If the lamp lights up or the tester beeps to notify you that the fuse is intact, you should continue searching for the problem. Otherwise, simply replace the insert.
Never install a fuse with a different rated current, and especially do not use various “bugs”. This will jeopardize the entire on-board circuit of the vehicle. And from a fire safety point of view, this is unacceptable.
Why does a fuse blow?
Having determined that the cigarette lighter on a VAZ-2114 does not work due to a blown fuse, it is worth thinking about the cause of this malfunction, because with normal operation of the on-board network, the fuse link can last for years. Its failure can be caused by a short circuit in the motor circuits of the interior heater, windshield washer, glove compartment light, or rear window heating relay. The fact is that the safety of all these circuits is ensured by the same fuse that ensures the safe operation of the cigarette lighter.
Another reason for the fuse link to burn out may be the inattention or negligence of the car owner himself when operating additional electrical appliances. If you recently vacuumed the interior of your car or inflated the tires with a compressor, connecting the equipment to a “car socket,” and then the VAZ-2114 cigarette lighter stopped working, you can be sure that it was these devices that contributed to the failure of the fuse.
When using such devices, it is necessary to take into account the amount of current consumed and not allow it to be greater than that of the machine’s on-board network.
Auto-assistance
In modern car operating conditions, drivers in most cases use the VAZ-2115 cigarette lighter socket not for its intended purpose, but as an outlet for connecting additional devices to it, as a power source, which are now sold in abundance in Russian automotive spare parts stores . But those drivers who do not think about the consequences of such actions often pay for it with repairs related to replacing the cigarette lighter socket or even repairing the mounting block.
The main reason for the failure of the cigarette lighter is that the plugs of additional devices, especially imported ones, through which they receive power, although slightly, still differ in diameter and the length of the protrusion of the central contact, to which the positive must be supplied from the current source.
If the central contact of the plug is slightly short, then when it is installed in the cigarette lighter socket, the antennae attached to the positive contact of the cigarette lighter socket move apart. This can lead to these antennae touching the body of the cigarette lighter socket, to which the wire going to the ground of the car is connected. As a result, a short circuit occurs and the fuse protecting this electrical circuit blows.
The driver, after turning on the headlights, sees that the lighting of the cigarette lighter socket is working and believes that after his previous actions, nothing happened to the electrical circuit of the cigarette lighter and tries to reconnect an additional device to this socket, but it refuses to work. The driver's first thought is that this device is out of order. But he is misled by the lighting of the cigarette lighter socket, which is powered through another fuse F10 (7.5 A), so this lamp is on, although the cigarette lighter fuse has already blown.
To replace a blown fuse, you will have to open the cover of the mounting block, which has symbols that help the driver quickly find the fuse he needs. But the problem is that there is no cigarette lighter symbol on it and the driver will have to look for a diagram of the location of the fuses in the mounting block, from which it will become clear that this electrical circuit is protected by fuse F7 (30A). If, when checking this fuse, it turns out that it is safe and sound, then the driver will need to look at another fuse F4 (20A), which will probably be blown. This is what will have to be replaced. But why F4 burned out and not F7, you need to ask automotive electricians.
What does the radio have to do with it?
There are situations when the radio and cigarette lighter of the VAZ-2114 do not work at the same time. You say: what connection could there be here? That's right, it shouldn't exist. But some “electricians” or car owners themselves connect the power of the radio to the cigarette lighter contacts. This is much easier than running wires to the battery terminals. So it turns out that when the cigarette lighter fuse blows, the radio stops working. In this case, it is better to contact a qualified auto electrician to correct the situation.
Method No. 2
If you don’t have extra money for a tuning device with diodes, and we’ve already dismantled the torpedo. You can do “luxury tuning” of the backlight of the stove control.
- We take 10 centimeters of white LED strip and two pieces of 5 centimeters each, blue and red (the store even sells 5 centimeters each).
- We make this design:
- We glue pieces of LED strip onto the textolite plate (white on top, red and blue on the bottom) and attach them to self-tapping screws;
- You can also substitute bushings to bring them closer to the scale itself (but this is not necessary).
- We solder the wires from the tape (can be placed on terminals) to the standard backlight wires and be sure to insulate them with heat shrink or blue electrical tape.
- To prevent your eyes from being too blinding at night, we stick a film on the back side (for example: Oracal 8300 073), maybe in two layers.
- We collect. It should look impressive.
This is the philosophy of the domestic auto industry: they give you a foundation, and then you do it yourself. Here the backlight, here the headlights were replaced, the steering wheel is sporty, the suspension is lower. And look, the car began to drive better. But it’s still worth it, the cabin should be comfortable, it’s like a second home. After replacing the heater light bulb, you can light up the footwells and stick tape to the sills, so that when you drive, you can see from afar that the car is positively charged.
Cigarette lighter lamp
The reason that the cigarette lighter on the VAZ-2114 does not work may be a banal burnout of its backlight lamp. The fact is that the device circuit is designed in such a way that the voltage is supplied first to it, and only then goes to the positive contact of the glass.
In order to check the lamp, you will have to remove the so-called beard - the center console of the torpedo. It can be easily dismantled after unscrewing the four screws located on the sides (two on each side). When the console is removed, remove the lamp from its seat and “ring” the tester. If necessary, replace it and check operation by turning on the ignition and side lights of the vehicle. After replacing the lamp, test the cigarette lighter.
Additional block
It is located at the bottom right of the center console, behind the protective cover.

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.
Other causes of malfunction
Typically, a cigarette lighter failure is caused by a blown fuse. You can easily identify and fix this breakdown with your own hands. But sometimes it breaks for other reasons.
Therefore, if checking and replacing the fuse element does not help, you should pay attention to the following:
- Oxidation of contacts and loose contact connections. It is necessary to inspect the contacts and connections. If necessary, they should be cleaned of oxides and contaminants. To do this, it is recommended to use WD-40 liquid or kerosene and a soft, clean cloth. You also need to tighten all connections.
- Light bulb condition. You can check its functionality in the following way:
- Open the car hood;
- Remove the terminals from the battery;
- Remove the fasteners that hold the cigarette lighter housing;
- Remove the plastic casing;
- Pull out the light bulb;
- Inspect the lamp. Its malfunction is usually clearly visible during visual inspection;
- If the light bulb burns out, replace it with a new one that is known to be good;
- Connect the battery.
- Cigarette lighter functionality. A short circuit or breakage of individual parts could occur in it. Often a malfunction can be noticed by eye. If the problem is not noticeable, you should test the device using a multimeter. According to the readings of the device, it will become clear that the element is broken.
This part is usually beyond repair. Therefore, it will need to be replaced. This spare part is inexpensive and is sold in almost all automobile stores. As a rule, it is always available. Therefore, you don’t need to order and wait for it. These are the main reasons for the failure of this device. You can easily diagnose and eliminate them on your own. Malfunctions of this part usually do not require a visit to a service station. This may be necessary as a last resort, when all self-diagnosis methods have not led to a solution to the problem. The rules do not prohibit the operation of a machine with this breakdown. It does not harm the car at all and may cause virtually no discomfort. But despite this, it is advisable to repair the device within a reasonable time. After all, even if you and your passengers do not smoke or are accustomed to using a lighter, you may unexpectedly need to charge a dead mobile phone. It may be unexpectedly needed in the event of an accident or other emergency situation.
And, if this problem is accompanied by problems with other, more important equipment, there is no point in delaying repairs.
