Causes
Practice shows that there are two main reasons for cigarette lighter failure on a VAZ 2109.
| Cause | Your actions |
| Fuse burned out | You should look for the fuse inside the mounting block. Depending on the year of manufacture of your nine, the fuse for the cigarette lighter is designated F4 or F10. If it burns out, remove the fuse from the mounting block, replace it with a new one and watch to see if the situation repeats. If it burns out again after a while, this indicates a shortening in the wiring. The peculiarity of this fuse is that it is responsible for several devices connected to it at once. Therefore, check the condition of the remaining elements. Maybe it's because of them that the fuse melts, and not because of the cigarette light |
| Poor contact | It may be partially damaged or absent completely. Remove the cigarette lighter, check whether the wires are seated properly on the terminals, and whether the device is loose. A visual inspection is good, but it’s better to be more precise. Take a multimeter, turn it into voltmeter mode and check what voltage is between the black and red wires. If the device shows 12 volts, look for the source of the problem in the cigarette socket. If there is no voltage, there is a break in the wiring. |
Cigarette lighters are designed for a certain load, exceeding which leads to failure of the unit. When developing the VAZ 2109, engineers at that time could hardly take into account that the socket would be used to connect portable compressors, powerful multimedia centers and other energy-consuming equipment.

Removal instructions
Armed with the tools, you can begin the repair. Before removing the cigarette lighter of the VAZ 2109, you must open the hood and remove the negative terminal from the battery. This will eliminate the possibility of a short circuit during removal.
- Unscrew the two fastening screws on each side of the decorative panel.
- Disconnect the wires of the control buttons.
- We remember where the plus of the contact chip is and take it out.
- We remove the cigarette lighter from its seat for subsequent repair or replacement.
Repair
If cigarette lighter failure cannot be avoided, you need to take troubleshooting steps. To do this, use the following algorithm of actions.
- Check the current state of the fuse, as well as the fuses adjacent to F4 or F. In some cases, the melting of one provokes deformation of other fusible elements.
- If replacing the fuse does not give the desired result, you will have to disassemble the cigarette lighter.
- Remove the cigarette lighter completely. Connect a test light to the socket located on the back of the unit and turn on the ignition. If the lamp lights up, this indicates the presence of electricity in the circuit. You'll have to disassemble the cigarette lighter. You were able to determine that the problem was in it, and not in the electrical wiring.
- Unscrew the fastening nut from the back of the cigarette lighter. But first sketch or photograph the position of the contacts before disassembling the assembly. This way you won't have any problems during the reassembly process.
- Unscrew the nut, bend the metal component away from the plastic element, and disconnect the metal components.
- Now you have a mica plate in front of you, which acts as a semiconductor. It needs to be dismantled.
- Next, we assemble the assembly in the reverse order, only without the plate. To install the cigarette lighter, you will have to work a little with a file, removing some of the metal for a comfortable fit of the element.
- A destroyed semiconductor is the most rare problem with cigarette lighters on the VAZ 2109.
- A more common problem is oxidation of contacts or a loose terminal.
- Therefore, remove the cigarette lighter and visually inspect the condition of the contacts and connectors. If you suspect a malfunction, disconnect all contacts, clean and reinstall everything. This also applies to terminals.
- Or another option is a violation of the integrity of the electrical wiring. This is not the rarest case that will require you to ring every wire going to a faulty car unit. After this, you can verify whether there are breaks or short circuits in the circuit. Damaged wires are replaced with new ones.
Repair work
When working with wiring, terminals and the cigarette lighter in general, be sure to follow safety precautions. Car electrical repairs involve potential risks, so follow the instructions carefully or leave the work to a professional.
Operating rules
If at some point the cigarette lighter stops working, what will happen? All your additional equipment will no longer receive power. As a result, you will be left without a media center, navigator, will not be able to charge your phone, and so on.
There are several important rules that are recommended to be followed when operating your VAZ 2109 equipped with a cigarette lighter.
- It is not recommended to connect compressors directly through the cigarette lighter, which many people use today to pump up their tires on the road. It is better to connect it directly through the battery. Such devices consume a lot of energy and create an impressive load on the vehicle's electrical wiring. At some point it may melt or a fuse may blow.
- Do not try to insert devices whose connectors are larger than the size of the cigarette lighter into the cigarette lighter socket.
- Do not connect metal objects. Also, when connecting the device, do not use equipment that has metal rings on the body. They often fly out, resulting in a short circuit. At best, your battery will quickly run out.

And what's behind it?
Malfunctions of the cigarette lighter and its socket
If the inspection of the fuse shows its proper condition, but the device, nevertheless, does not work, it is necessary to ring the circuit supplying voltage. Take a portable voltmeter and measure the voltage between the black and red wires that go to its socket. The voltage should be approximately 12 V.
If there is no voltage, inspect the contacts, move the contact groups, and clean the wires from acidification. Make sure that the contacts have not become loose due to vibration during operation. If voltage is properly supplied to the socket, but the cigarette lighter itself does not work, then you have a choice of one of three options.
| Options | Possible actions |
| Coming to terms with a broken device. | Using its socket to connect current-consuming agents. |
| Replacing the VAZ 2109 cigarette lighter with a new one. | This is the best way out of the situation. |
| Attempting to repair the device. | The third option is the least rational. The cigarette lighter circuit is such that most often the thermoelastic element fails. As a rule, it is not sold separately at all. |
It is easier to buy a ready-made cigarette lighter than to repair a broken one.
Why is a cigarette lighter used in a car?
Nowadays, its nest is increasingly being used for other purposes than its intended purpose. Almost forty years ago, when AvtoVAZ designers conceived the first cars of the Samara family, which included the VAZ 2109, they could not imagine how else this unit would be used.
DVRs had not yet been invented, and the question of where to turn on the recorder was not raised in principle. In the same way, there was no task to connect satellite navigation equipment to the on-board network - there was no such equipment at all. And there was no need to even charge cell phones due to the lack of such in nature. Now it’s all there and is powered by the cigarette lighter.
Such abnormal operation leads to an increase in the load on its nest. This may lead to its failure. Particularly dangerous in this sense is a portable electric compressor, which has become widely used by motorists today. On long and even short trips, drivers often have with them such a compressor, which allows them to drive for quite a long time on a punctured tubeless tire, periodically pumping it up and leaving the issue of repairing the wheel until the tire shop. Care should be taken when making such swaps.
Remember that the cigarette lighter is only designed to light a cigarette, but not to pump up a completely flat tire over and over again. At the very least, for such a swap you should connect the crocodile clips to the battery terminals, and not to the cigarette lighter socket.
Repair
As practice shows, in some cases, if the cigarette lighter stops working, the problem must be looked for in the socket.
In this situation, most likely, the washer made of tin fails - it simply melts from excessive load. The thing is that it is with its help that the voltage reaches the central contact of the cigarette lighter device. To fix it, you will need to remove the part that has become unusable. The main thing here is to act extremely carefully so as not to spoil the porcelain base - it is quite fragile. Without this washer, the cigarette lighter will function normally. To restore functionality, sometimes it is also necessary to remove the semiconductor wafer. Here you will have to act in the following order:
- before disassembling the connector, it is worth photographing the location of the wires on the contacts - this will help you assemble everything the first time without errors;
- the fastening nut holding the socket on the panel is unscrewed;
- inside there is a plate made of mica - it needs to be pulled out;
- then the connector is assembled completely, but without the above-mentioned part.
In addition, quite often loss of contact occurs due to banal oxidation of the terminals or a broken connection. For this reason, during repairs, attention is always paid to cleaning all connectors and connectors. Remove oxides with a regular student's eraser.
The break is identified by inspection. To avoid confusion, it is better to mark the tested wire with something. It will be faster to check with a multimeter set to Ohms. In general, there are not many of them, and the test is carried out quite quickly. All damaged veins must be replaced with new ones.
