What is a cigarette lighter
Structurally, the cigarette lighter consists of two main parts: a glass and an insert. The first element is made of metal and has a cylindrical shape. In its lower part there is a contact to which voltage is supplied from the positive terminal of the battery. The body of the glass is connected to the “ground” of the car.
The insert is also made of metal and has a cylindrical shape. There is a special spiral placed inside it, which heats up when current passes through it. The upper part of the insert is equipped with a plastic cap.
To ensure that the cigarette lighter can be easily found at night, the glass is equipped with a transparent plastic rim, under which there is a backlight. It lights up when the side lights are turned on.
Removing and replacing the cigarette lighter
Before repairing, you will need to stock up on suitable tools. Required:
- Phillips and standard screwdriver;
- protective gloves.
To fix breakdowns you will need:
- multitester;
- blowtorch with solder;
- heat shrink tubes, electrical tape;
- wire cutters;
- needle file
- Open the hood and remove the negative terminal from the battery. You can also remove the fuse from the mounting block that is responsible for the cigarette lighter of the VAZ 2110.
- We unscrew the four fasteners of the tunnel covering and remove both parts of the lining.
- Disconnect the three-pin plug going to the cigarette lighter.
- Remove the lining under the handbrake lever.
- Remove the gearshift lever cover.
- We move the seats back, and then unscrew the three fastenings of the upper part of the tunnel and remove it.
- Pull out the cartridge.
- Use a flat-head screwdriver to pry the cigarette lighter latch so that it comes out of the seat.
- We remove the nest from the cladding for subsequent repairs.
How does a cigarette lighter work?
The principle of operation of the cigarette lighter is quite simple. When we press on the insert, it goes deeper into the glass and is fixed inside it using specially provided bimetallic plates. An electric current begins to flow through the coil, heating it. When the temperature reaches a certain value, the plates expand under the influence of heat and the insert returns to its original position. Taking it out of the glass, we have the opportunity to light a cigarette from a red-hot spiral. But this is for those who smoke. And for those who use the device as a power outlet, simply plug the plug of any of the additional electrical appliances into the glass, and while it is working, it will be powered by a battery (generator).
Fuse
In a situation where the VAZ-2110 cigarette lighter does not work, the first thing you need to do is check the fuse. It is this device that most often fails. The VAZ-2110 cigarette lighter fuse is located in the main mounting block, which is located in the engine compartment. It is designated F-18 on the electrical diagram and is typically rated at 25 amps.
By the way, it is not at all necessary to immediately climb under the hood. If the VAZ-2110 cigarette lighter does not work, the serviceability of the fuse can be checked by turning on the heater fan. Just press the launch key in any mode. If it works - the VAZ-2110 cigarette lighter fuse is working, if it doesn’t work - open the hood.
You ask: “What does the fan have to do with it?” The fact is that the F-18 fuse is also responsible for protecting its electrical circuit, and also for illuminating the glove box. To make sure, turn on the lights and open the glove compartment. The light doesn't come on - let's go look for the fuse!
You can check the F-18 fuse link using a multimeter turned on in tester mode. Remove the fuse from its socket and ring it. If a malfunction is detected, replace the insert, observing the rating.
Video with important moments
Below are videos that will help you figure out how to replace the cigarette lighter on a car with a Europanel.
The highlight of this article will be the VAZ 2110 cigarette lighter. Probably now you can’t find a driver who doesn’t use it. Unlike the old days, when it was mainly used to light a cigarette. Since every day there are more and more gadgets that take power from the cigarette lighter, the load on it is increasing. Therefore, cigarette lighter breakage became a common problem.
Therefore, very often motorists wonder how to replace the cigarette lighter. In this article I will tell you not only about replacement, but also about how to check the cigarette lighter.
Most often, a cigarette lighter breaks down not because it is used for its intended purpose (lighting cigarettes), but because various devices that require high current are inserted into it. And some also put tees on the cigarette lighter, which has a very detrimental effect on its operation.
Today, the cigarette lighter is an integral part of every car, where the cigarette lighter of the VAZ 2110 will be no exception. In the last century, it was required only as an obvious way to light a cigarette and was used mostly by smokers, but those days have sunk into oblivion. Nowadays, this is a great way to recharge your phone or connect a navigator, or even an entire DVR and other electrical equipment, instead of using the VAZ 2110 cigarette lighter for its intended purpose.

Device diagnostics
No matter how ironic it may sound, most VAZ 2110 cigarette lighters break down due to use other than their intended purpose, in particular, car owners begin to connect various types of electronics, which in turn consume large amounts of electric current. Any electrician will say that no matter how it sounds, in reality the electrical circuit is quite simple and the VAZ 2112 cigarette lighter does not require any special skills.
Disassembling the center console
Further diagnostics of the device requires its removal. But how to remove the cigarette lighter of a VAZ-2110? Some specialists manage to remove it from the facing panel without dismantling it by picking it out with a screwdriver, but why deform the plastic if it takes no more than five minutes to remove it? Yes, and for this you only need a Phillips screwdriver.
The work order is as follows:
- Unscrew the screws securing the left and right trims of the center console.
- We disconnect the connecting blocks of the cigarette lighter wires and its backlight (it is recommended to disconnect the negative terminal from the battery in advance).
- Push up the front trim (under the handbrake lever). Remove the cover.
- We remove the gear shift knob, and then its cover.
- Unscrew the central screw securing the tunnel lining.
- Move the front seats all the way forward.
- We unscrew the screws for the rear fastening of the upper cladding and dismantle it.
Dismantling the tunnel on a VAZ-2110
To remove the tunnel you will need:
- Remove the facings by unscrewing two bolts on each.
Use a Phillips screwdriver to unscrew the screws and remove the tunnel lining.
On the right side we find and disconnect the pads.
Remove the cover under the handbrake.
Remove the cover by prying it with a flat screwdriver in four places.
Removing the cigarette lighter
To remove the cigarette lighter itself you will need:
- Pull the cigarette lighter out of the socket by squeezing the connectors.
Remove the lamp screen by squeezing its claws.
Installing the cigarette lighter is carried out in the reverse order.
When installing a new cigarette lighter, observe the polarity of the terminals.
Quick method
If you look at this procedure as it is described in the User's Guide, the work will seem complicated. That is why for many it is a problem how to remove the cigarette lighter from its socket without removing the tunnel itself . There is little space for such manipulation and there is no access to the cigarette lighter from different sides. But there are certain points that will help you cope with the task.
You should insert your finger into the cigarette lighter socket and pry off the cigarette lighter itself with a screwdriver. If you manage to remove the cigarette lighter from its socket, then it can be changed. Installation is also carried out in reverse order.
If the cigarette lighter socket is hanging into the hole, you may be able to remove it without dismantling the tunnel.
Checking the condition of the wiring and contacts
Having removed the center console panel, the first thing you need to do is inspect the contacts of the blocks connecting the power wires of the cigarette lighter and its backlight. If everything is in order with them, put the terminal on the battery, turn on the ignition and check if there is voltage on them. Its absence may indicate an open circuit in the cigarette lighter circuit. In this case, you will have to check the wiring from the blocks to the mounting block. This can be done by ringing the conductors.
If you find that the contacts in the pads are oxidized or burnt, clean them with fine sandpaper, and then check the functionality of the cigarette lighter. If everything is fine with them, inspect the connectors on the device itself. It has three contacts: two “pluses” (for the lamp and glass) and one common “minus”. If necessary, clean the contacts with sandpaper.
Spiral
If the VAZ-2110 cigarette lighter does not work, the reason may lie in the spiral of the insert. Its burnout is most often caused by a malfunction of the bimetallic plates. Over time, they lose their properties (bending and unbending under the influence of temperatures), which leads to the fact that the insert does not “jump” out of the glass in a timely manner. Naturally, this leads to overheating of the coil and its burnout.
It is quite difficult to check the serviceability of this element, since a broken thread can short to ground. Trying to restore the spiral is also a thankless task. It's better to buy a new cigarette lighter. Moreover, it costs around 300 rubles.
Reasons why the cigarette lighter does not work
There are several situations why a device may fail. The most common reasons why the VAZ 2112 cigarette lighter does not work:
- short circuit;
- broken cigarette lighter wiring;
- blown fuse;
- weak contact;
- faulty spiral;
- burnt out backlight bulb.
Each breakdown situation is discussed in detail below.
The fuses on the cigarette lighter are burning
If the device on a VAZ 2112 stops working, then a burnt-out protective element may be the cause of the malfunction. The vehicle circuit in this area is protected by a 25 amp fuse. This means that devices with a total power of more than 300 W (12 volts * 25 amperes = 300 watts) cannot be connected to the cigarette lighter socket.
Otherwise, the protective element will burn out. A hint that it is the fuse that has “gave up” is the failure of the heater fan. If it does not work, it should be replaced. The location of the mounting block is to the left of the steering column, behind the decorative panel trim.
The element with index F-18 must be replaced. The fuse rating is 25 amperes. It is prohibited to install parts designed to carry high current. This may lead to short circuits, damage to wiring cables, and fire.
Broken or shorted wiring
You need to check where the fuse for the cigarette lighter of the VAZ 2110 is. If it is intact, but often burns, then you should check the serviceability of the cables. Due to a mismatch in the rating of the protective element or connecting too powerful devices, the wires may burn out, which causes a short circuit or damage to the cigarette lighter. For diagnostics, you will need a multitester, which needs to ring all the wires suitable for the element, finding out their condition.
Replacing the cigarette lighter VAZ-2110
If you decide to replace the cigarette lighter, you will have to perform the steps described above to dismantle the top panel of the central tunnel lining. Before connecting the cigarette lighter to the VAZ-2110 and installing it in place of the old one, you should make sure that it is working. To do this, simply connect the connectors of the power cables of the device and the backlight to their contacts, turn on the ignition and carefully press the insert into the glass. Wait a little while the coil heats up. If the insert “jumped out”, then the device is working.
Replacing the VAZ-2110 cigarette lighter must be carried out with the negative terminal of the battery disconnected! To do this, disconnect the non-working device from the power cords. Next, use a screwdriver to press the latch of the cigarette lighter socket on the back side of the facing panel and push the glass forward. Install the new cigarette lighter in the reverse order.
Causes of cigarette lighter malfunction and fuse diagram
Cigarette lighter for VAZ 2110
The cigarette lighter on a VAZ 2110 most often fails because they try to use it for other purposes and connect several devices that consume high current to it at once. It is in this case that one of the fuses may burn out, which in the VAZ 2110 is marked as F18.
Fuse box for VAZ 2110 car
This fuse can pass a current of 25 amperes. If this limit is exceeded, the device burns out. That is, to find out whether the cigarette lighter is working, you first need to look into the fuse box and check the integrity of F18.
There is another way to check the serviceability of the cigarette lighter.
You should try turning on the heater fan. At first glance, there is no connection between these devices. But the fact is that both the fan and the cigarette lighter are on the same fuse - F18. And if it turns out that both devices do not work, then the problem is definitely in the fuse. And if the stove works normally, then the problem is not in the F18, but in the cigarette lighter itself.
But even in this case, you should not rush to remove this device. It’s better to look into the safety block again and check the integrity of fuse F6. Sometimes (very rarely) the cigarette lighter does not work precisely because of F6, and by replacing it the problem goes away.
