Even non-smoking car owners use this device. After all, the functionality of the VAZ 2114 cigarette lighter is much broader than the name might suggest. A lot of additional devices can be connected to the device socket:
- charger for phone, tablet, laptop or other devices;
- navigation;
- motion recorder;
- compressor with wheel inflation.
However, over time, the cigarette lighter on the VAZ 2114 may fail, which will lead to a lot of inconvenience. It is not difficult to repair an element or replace a spare part with a new one yourself. Detailed information on how to identify a fault on a VAZ 2114, remove the cigarette lighter yourself, diagnose an element, change a part is described below. Photos and videos are provided to help you understand the instructions.
Design and principle of operation
To find the reason why the cigarette lighter does not work, you need to understand its structure and principle of operation. The small device is made in a plastic case, inside of which there is a metal spiral. The functions of the heating element are performed by nichrome or other material with increased resistivity. The product is connected to the corresponding socket on the dashboard, and the positive contact is connected to the heater.
When heated, the nichrome spiral turns red. The system is equipped with a thermal relay that turns off the power supply when the permissible temperature threshold is exceeded.
The cigarette lighter socket is illuminated, so finding it in poor lighting conditions is quite easy. There is also a 10 A fuse in the socket.
Before turning to specialists with the question of why the cigarette lighter stopped working, you should consider the main reasons for this incident.
Let's summarize
Obviously, the procedure for replacing the cigarette lighter is quite simple, even a beginner can do it. But you need to understand that the cigarette lighter will have to be changed often if the current consumption increases above 25 amperes. Once this value is reached, the entire procedure described above will have to be performed again, since the node will inevitably fail. The most common reason for this is connecting multiple devices at the same time. You should not use tees, and you should always know exactly how much the device you want to connect to the cigarette lighter consumes. This will extend the life of both the unit itself and the fuses.

Why doesn't the cigarette lighter in the car work?
There are several reasons that explain the loss of functionality of a car cigarette lighter. Among the most common are:
- Burnout of the socket.
- A foreign object has entered the socket and is preventing connection.
- Loosening or deformation of the “antennae” of the socket.
- Damage to the fuse in the block.
The last element is considered the most vulnerable to breakdowns. It often fails due to overload when the driver connects powerful electrical appliances, including:
- Car refrigerator.
- Compressor.
- Mattresses.
- Pumps.
- And others.
Removable devices are able to work with low-power gadgets (laptops, smartphones, tablets). If you expect to connect “heavy” devices, it is better to connect them directly to the battery. This process may seem complicated, but the main thing is to install the terminals correctly, observing the polarity.
In addition to problems with the fuse, the following causes of malfunction are distinguished:
- Short circuit in the wiring. If the product frequently burns out or is exposed to extreme heat, you should check the wiring. Before this, you need to remove the part from the socket and evaluate the condition of the contacts. A multitester and a detailed wiring diagram are used for testing. In the event of a cable break, the fuse will trip.
- Poor contact. During operation, the sockets wear out or oxidize. As a result, the device stops heating and the current supply is suspended. To restore functionality, do a simple cleaning of the device.
- Damage to the nichrome spiral. The heating element also burns out. If this problem occurs, you will have to purchase and replace the part yourself.
How to check
Finding out whether the cigarette lighter in your car is working is easy. The first sign of a breakdown is lack of response when connecting external devices. Associated symptoms manifest themselves in the form of the clock, dashboard backlight, radio and other standard devices turning off.
To check the functionality of the part, remove the mounting block and evaluate its condition. The placement of the block depends on the design features of the machine. In VAZ cars it is located on the front panel.
If the cigarette lighter does not work even though the fuse is working, pull out the wires and check their integrity with a multimeter.
Connection diagram
Connecting the cigarette lighter is not difficult. The device is connected to the on-board network with only three wires.
- Black wire - the ground of the car is connected to the cigarette lighter body.
- Red wire – power is attached to a terminal at the end of the housing. This threaded clamp also serves as a fastening for the heater retainer, so power is supplied to it as well.
- Yellow wire – power supply for instrument lighting is connected to the lamp socket. Ground, which is supplied through its contact with the cigarette lighter body.

What to do
Fixing cigarette lighter breakdowns does not take much time. However, the car owner needs to get a general idea of the repair and draw up a step-by-step action plan.
The simplest solution is to seek help from specialists. An experienced service center employee will return the product to working order in a short time. However, you will have to pay for such a service.
To do all the work yourself, follow the following instructions:
- Make sure the fuse is in the correct location. According to the scheme, it should be fixed in a common box and indicated by the symbol of a smoking cigarette or the inscription “Cigar”.
- If a part fails, replace it with a new one.
- If the product is working properly and continues to conduct current, evaluate the condition of the socket.
- Pay attention to the interior of the nest. It may be clogged with some debris. To remove a foreign object from the socket, you need to use tweezers. However, the action must be performed with extreme caution.
If there are traces of burning on the cigarette lighter, you will need to buy a new product. If there is a soldered wire, it is enough to solder it.
Required Tools
To repair the cigarette lighter, you should prepare the following tools:
- Tweezers.
- Screwdriver (phillips or flathead).
Also, a flashlight, a multimeter and a printed wiring diagram may be useful for the upcoming work.
How to remove the cigarette lighter
If you have found the cause of the cigarette lighter failure and prepared the necessary equipment, proceed to disassemble the part. The dismantling process involves the following steps:
- First you need to open the hood and remove the negative terminal from the battery.
- Next, you need to disassemble the facing panel to gain access to the socket connection connector.
- Then you can unscrew the screws and disconnect the block.
- The next step is to dismantle the metal cigarette lighter tube using a screwdriver.
- After removing the part, you must turn off the backlight.
A serviceable element can be repaired, but a burnt-out element will have to be replaced.
Car cigarette lighter button repair
Often the device stops working due to damage to the power button.
The problem is solved by dismantling the failed key and then restoring or replacing it.
The repair process does not take much time and is done with your own hands.
Cigarette lighter head repair
In some cases, it is necessary to perform partial repairs of the car cigarette lighter. To do this, the element is dismantled according to simple instructions and checked for defects under the housing. Inside the part there is a miniature mica plate, which acts as a semiconductor and often fails. The product must be removed, repaired, and then put back.
Step-by-step instructions for replacing light bulbs in the dashboard of a VAZ-2114
- We release the decorative cover of the front panel. For this we need screwdrivers: a short Phillips and a flathead one. Lower the steering column to the lower position using the height adjustment lever to keep it out of the way. The photo shows the mounting locations for the casing:
- There are four screws on the bottom of the visor and above the steering column. Unscrew them with a short Phillips screwdriver.
- Using a flathead screwdriver, pry off the decorative cap to the right of the row of switches. There is another fastening screw under it.
- Also, remove the handles from the heater switch and damper control sliders by pulling them towards you.
- If you have a car radio, you will also have to remove it.
Unfortunately, complete dismantling is not possible. Arrows indicate locations for removal - Pull the front panel cover towards you. He must move. There is no need to remove it completely - there will be enough space to access the mounting screws on the sides of the instrument cluster.
Carry out your actions carefully - Unscrew the fastening screws with a long screwdriver. The combination will be released and you can tilt it towards yourself. Pull out the two blocks with wires. Don’t be afraid to mix them up - there is a color marking, and the asymmetrical shape of the connector will prevent you from connecting it incorrectly.
The arrow indicates the location of the cartridge handle - On the back cover of the instrument cluster there are cartridge handles. Arm yourself with small pliers. This will make it easier to unscrew them. To release the cartridge, half a turn counterclockwise is enough. You can safely take out all the cartridges - they are the same. Next, you can check the lamps with a tester and replace the burnt ones, or replace them all with LEDs at once. Try to ensure that they fit tightly in the cartridge, otherwise the contact will be unreliable.
- We reassemble in reverse order. We insert the cartridges into the seats so that the antennae fall into the grooves, carefully turn them with pliers until they stop. We connect both blocks to the connectors of the instrument cluster.
- Let's check if all the lamps are working:
- raise the handbrake and turn on the ignition: so let’s check the handbrake, generator, oil pressure and check lamps,
- turn on the hazard warning lights - check the warning lamp and direction indicator lamps,
- pull the headlight switch lever towards you - temporarily turn on the high beams, check the warning lamp,
- turn on the dimensions - see if the scales are evenly illuminated, and if the warning lamp, if any, is on.
If everything works correctly, we fix the instrument cluster and the front panel casing, and replace the heater switch handles and damper controls.
Check the brightness and functionality of all devices
Congratulations, now the instrument lighting and warning lights are working properly, and you will always be aware of what is happening with the car. The overall aesthetics of the front panel will also improve - the evenly lit front panel looks beautiful.
