Many components related to the electrical system in cars are interconnected, so you should not be surprised by frequent complaints on specialized forums that the cigarette lighter and radio of the VAZ 2114 do not work at the same time. In most cases, the cause of the malfunction is found out quickly enough and can be eliminated relatively easily by the car owner on his own. .

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.
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.
What to do if the safety device malfunctions?
The answer is also not difficult. Replace the burnt device with a new one that fully complies with the technical parameters of the previous one. It is not expensive and is sold in all auto parts stores. As a little advice. Have a spare fuse or even several. Since they fail quite often, especially in winter and summer. And also when repairing a car. This is explained by the increased load on the electrical system when the air conditioning and interior and seat heaters are running. Negligence when disconnecting the battery (de-energizing the network) during minor repairs, etc.
The VAZ-2114 cigarette lighter does not work: reasons
The most common reason why an electric lighter and a record player stop working at the same time is a blown fuse. The fuse link in VAZs of these models is common for the circuits of the car player, rear window heater, interior heater and electric lighter. If a short circuit or malfunction occurs in each of these devices, the insert is destroyed and all listed circuits are switched off.
The reasons why the cigarette lighter and radio fuse fails are often as follows:
- destruction of the fuse element due to a short circuit or malfunction of devices connected through it;
- contact failure in the safety panel (due to shaking, mechanical impact, etc.);
- oxidation or burnout of contacts due to frequent power surges in the network;
- burnout of the cigarette lighter lamp;
- loose contact or burnt out spiral.
To determine the malfunction, you need to visually inspect and check with a tester the fuse-link and the devices whose circuits it disconnects.

Which fuse is responsible for the VAZ 2114 radio?
Some VAZ-2114 owners encountered such a paranormal phenomenon when the radio and cigarette lighter stopped working immediately. Naturally, the connection is even, although not immediately visible. But how to find the nature of the guilt and, of course, eliminate it at home.
Structurally the situation is that the radio contact strip and the cigarette lighter are in the same branch, so if one doesn't work, the other shouldn't work.
And since this is AvtoVAZ, there is nothing to be surprised about and this can be a fairly common occurrence.
The connection between the radio and the cigarette lighter is the same in the design itself. Yes, several electronic devices are immediately connected to one branch of the electronic circuit, and in addition to those already indicated, a rear window defroster and a defroster can be connected.
Assembled assembly block from the car.
Since the radio and cigarette lighter are electronic devices and are fed into the same branch of the on-board network, it is likely that faults must be detected in the electronic part.
The main cause of the error is the following fuse , which cannot withstand the load that the user places on this address. Consequently, connecting additional devices causes a short circuit, which will be a prerequisite for the fuse to blow. However, in practice, these are not all the tasks that will be associated with a broken radio and cigarette lighter.
What to do, let's see what other prerequisites are necessary as a result of the operation:
- Connecting contacts to a security group.
- Oxidation of contacts.
- Broken wire.
- Short circuit.
- Blown light.
Now that the basic premises have been addressed, we can move directly to the remedies.
The radio does not work
It is worth warning the motorist about this. If he does not understand the design or is not sure that he can fix the problem without outside help, it is recommended to send an expert to a car service center.
What we need to do is understand what are the ways to deal with snowballs.
I disassembled the dashboard and looked for defects in the fuses and cigarette lighter.
The most common cause of faulty other electrical circuits, faulty individual parts, is a faulty fuse.
Here you must first find the reason.
There is a socket with a fuse box for the radio and cigarette lighter. F4. The fuse marking on a personal computer is preferably 20A.
However, not often, and it can withstand the load placed there. Yes, frequent and extensive introduction of additional devices leads to frequent burnout of this element. To check, you must pull out and look at the fuse itself. If necessary, the element is changed to a new one, if your client needs to do something, it worked, then the reason was found. However, if the problem persists, it should be found elsewhere.
Checking the fuse group
contact Group . Another common cause of an open circuit. In most VAZs, the fuse contacts with the block, as it is called in the diagram, are wired or burnt out, and melted plastic can break the contacts.
Troubleshooting requires ensuring that our client remains in the lead on the contact pads that go from the radio and lighter to the fuse box. What is required such as oxidation and lack of contact will render the parts unusable.
Another condition is a break in the power wires. So to troubleshoot, you will need a tester to call and have a broken wire . When using electrical tape, it is recommended not to replace the wire the old "old fashioned way" but to replace it with the new one. It won't take long as it's better to do everything possible to short circuit and get into a lot of trouble.
A place where the cigarette lighter often fails.
The worst thing that happens is a short circuit. A necessary condition for this phenomenon is that frequent insertion of the cigarette lighter weakens the socket so that the contacts cross and cause a short circuit.
Standard cigarette lighter. it's just a breakdown of the VAZ-2114.
It's easy to troubleshoot here. change the jack. But often motorists take a low-quality and affordable product that repeats this function in a short time.
Ignition of the cigarette lighter at night VAZ-2114.
The backlight is in the same circuit, because the combustion of this element becomes a prerequisite for the immediate failure of the radio and cigarette lighter. So if you change the subject, there is an opportunity to improve the situation.
Where is the fuse located
Manufacturers of VAZ-2114 did not install acoustic systems on their cars. Because of this, vehicle buyers were forced to independently search for suitable radios and install them with their own hands.

Electricity is supplied to the installed device through the cigarette lighter (an element with a high energy consumption). To avoid short circuits and surges in the circuit, it is necessary to install additional protection that is responsible for the radio and turns it off in the event of an unforeseen situation.
This fuse is located in the wiring box, which is located in a special block under the hood of the car. To access it, you need to remove the cover and find the desired part among many others. On most VAZ models it is located third from the bottom (in the left row) and is marked F7.

Troubleshooting the cigarette lighter and radio
Before starting repairs, you must find the fuse. Open the rectangular hatch to the left of the steering column of vehicles of the indicated models. Inside it there is a block of all fuse links of automotive electrical wiring. The element in the socket marked F4 is responsible for the operation of the cigarette lighter and radio on the VAZ-2114.
If the fuse looks normal externally, you can determine the open circuit in this place with a simple screwdriver tester. The light on the probe lights up when the element is working. Otherwise, you need to find a new 20 A insert in the repair kit, remove the faulty part from the socket and insert a new one. In most cases the problem is resolved.
If the safety element is working or has been replaced, but the cigarette lighter and radio do not work on the VAZ-2114, do the following:
- Check the radio's own fuse. It turns off only the player, so the inspection is carried out in the case when, after replacing the element in the block, only the cigarette lighter and electrical equipment for heating work (general: body and heating system), but the tape recorder is silent. The burnout of its safety element may indicate a breakdown in the music console, so it is recommended to have it checked in a workshop.
- Inspect and check the contacts of the fuse socket in the block. This is done if, after replacing the insert, the functionality of all devices is not restored. Tighten loose contacts and clean them from carbon deposits.
- Inspect the cigarette lighter and check it with a tester. The peculiarity of the backlight lamp is its serial connection into the electrical circuit. Its burnout causes a break in the circuit of the entire device, and additional electrical appliances connected to the socket (for example, charging a phone) do not work. A working cigarette lighter will work after replacing the lamp.
- Burnout of the heating coil is determined with a tester by applying its probes to the cigarette lighter contacts. In a faulty device, the resistance scale (Ohm) will display the value 0 (short circuit) or 1 (burnout). Indirect evidence of a malfunction is the additional devices connected to the socket: if the coil of the cigarette lighter itself burns out, then its socket remains operational and the phone will charge normally. The malfunction can only be eliminated by replacing the device. When purchasing a new one, it is advisable to immediately check its performance.
Sometimes devices stop working due to a break in the wires running from the fuse block to the cigarette lighter or radio. But in this case, only 1 device is always turned off, and the rest, connected through the same element, operate normally.
Additional recommendations
First of all, you need to avoid the temptation to solve the problem quickly by replacing the faulty fuse with something that comes to hand that can close the necessary contacts in the block.
For the same reason - in order not to provoke a more serious breakdown (fire, short circuit or melting) - you cannot get by with simply twisting the wires: you should definitely use a soldering iron with solder.
You should be careful when buying a new fuse or, especially, a cigarette lighter - low-quality counterfeits or uncertified products can fail immediately, so they should be checked in the store with a tester under load.
Mounting block VAZ 2114
Finally, before starting work on repairing electrical appliances, it is strictly recommended to turn off the power to the car by removing the terminals from the battery. If you are unsure of your abilities, it is better to contact a professional car service center, or at least carefully study the relevant instructions (you can find them for any VAZ model, including 2114, on the Internet).
Starter, ignition, rear fog lamp relay
In order to carry out quick checks and repairs, the ignition system relay is installed under the front dashboard of the car, behind the hood release handle. It is located just below the central dashboard. The module is closed with a plastic plug, which must be opened slightly to test for functionality.
Starter, ignition, rear fog lamp relay
Next to the indicated relay, there is a similar one for the rear fog lights and the starter.
The main task of the relay when igniting is to reduce the applied load to the contacts. When the engine starts, the relay turns off some electrical circuits in the vehicle system. The system is used not only in injection, but also in carburetor engines.
In the event of a malfunction or malfunction in the ignition system, it is necessary to monitor the operation of the relay. For this purpose, open the box and carefully remove the desired element. It is attached using contacts to special grooves. The first thing to do is look at the oxidation of the contacts, if necessary, clean them with a soft cloth or treat them with a special liquid.
To check functionality, you need to use a regular multimeter. We connect to incoming connections and check the numbers. If there is no short circuit when current is applied, it means the element is not working. Replacement is carried out in a similar manner. It is necessary to use a standard element with the number of amperes indicated on the housing.
