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. .

Where is the fuse for the cigarette lighter?
In many brands of cars there is a PP ( cigarette lighter fuse
) is located on the panel of the block, where all the fusible elements that protect the electrics are located. The block, depending on the car model, is located: under the dashboard of the car, under the hood, under the steering column.

Methods for solving the problem
Now that the main causes have been sorted out, you can move directly to elimination methods.
It is worth warning that if the motorist does not understand the design or is not sure that he can repair the fault on his own, then it is recommended to turn to a professional car service center.
So, let's look at what ways to deal with the malfunction.
Fuse
Disassembled dashboard while searching for fuse and cigarette lighter faults.
The most common cause of malfunction or inoperability of the electrical circuit of individual elements is the notorious fuse.
This is where you need to look for the cause first.
The fuse box socket – F4 – is responsible for the radio and cigarette lighter. The fuse marking in it should be 20A.
But it does not always withstand the load placed on it. Thus, frequent and large use of additional devices can lead to frequent burnout of this element. Therefore, to check it is worth removing and inspecting the fuse itself. If necessary, the element is replaced with new ones and if everything works, then the reason has been found. But if the problem does not go away, then you should look for it in other places.
Contacts
Checking the contact group of fuses for malfunction
A contact group is another common cause of a non-functioning electrical circuit. In most VAZs, the connecting contacts of the fuse with the block or in the circuit of the wire block oxidize or burn out, and molten plastic can interrupt the contacts.
To troubleshoot the problem, you need to check all the contact blocks of the wires that go from the radio and cigarette lighter to the fuse box. So, it is oxidation and insufficient contact that can lead to the inoperability of the elements.
Wiring
Another reason could be broken power wires. So, in order to find and fix the fault, you will need a tester that will test the wiring and find a broken wire . It is recommended not to fasten the wire using the old “old-fashioned method” using electrical tape, but to replace it with a new one. This will take little time, so it’s better to do everything in such a way that you get a short circuit and cause big problems.
Short circuit
Location of frequent failure of the cigarette lighter socket.
The worst thing that can happen is a short circuit. The reason for this phenomenon is that frequent use of the cigarette lighter loosens the socket and this can lead to the contacts crossing and causing a short circuit.
The standard cigarette lighter is just a disaster for the VAZ-2114.
Here, the treatment for the malfunction is quite simple - replacing the socket. But, often motorists take a low-quality and cheap product, which repeats the procedure after a short time.
Bulb
Cigarette lighter illumination at night VAZ-2114.
The backlight bulb is located in the same electrical circuit, so the burnout of this element causes a malfunction of the radio and the cigarette lighter at the same time. So, if you replace the element, you can correct the situation.
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.
Trouble-shooting
Having established the reason why the VAZ cigarette lighter and radio are not working, we correct the detected breakdown. The list is given in accordance with the listed faults.
- We remove the fuse box (the hatch on the left side of the steering column of the car). We remove the device marked F4 (20 ampere fuse), test it for serviceability with a simple screwdriver probe, if this moment is not visually determined. And we replace it with a new one from the mandatory kit for such cases.
- Check the conductivity of the contacts with a probe. If they are loose, tighten them.
- Strip or resolder the contacts, depending on the situation.
Paradoxically, a burnt-out light bulb breaks the contact circuit (a kind of fuse). Replace it with a working one of the same power.
A short circuit most often occurs due to a loose cigarette lighter socket and a malfunction of its heating coil. If you have the opportunity, then replace them with new ones or restore them to proper condition.
Expert advice
Professional automotive electrical repair technicians complain that even when carrying out repairs that are so insignificant in scope and complexity on their own. Some car owners manage to violate basic rules, thereby significantly aggravating the problem and transferring it to another, more complex (and expensive) repair category.
It is for this reason that we provide several recommendations for replacing and repairing car cigarette lighters.
No replacing fuses with improvised means (despite the advice of so-called experienced drivers). A single case of such a replacement cannot serve as a reason for its re-use.
A definite no to any direct connections (twists). All work must be done using a soldering iron.
When purchasing a new cigarette lighter from an unknown retail outlet, if possible, check its serviceability and quality, using a tester and visually.
Before working on any electrical appliance, be sure to de-energize the vehicle's electrical system. Otherwise, in addition to shorting, you expose yourself to the risk of electric shock.
Do not neglect to carefully study the instructions and any available information.
Don't be overly confident. If you doubt your capabilities, seek help from professionals.
Do not think that this problem is typical only for VAZ 2114 (2115, 2109, 2110, 21099) cars. The same malfunctions with some (minor) differences are often found in imported passenger cars. As an example, we can cite the Daewoo Matiz, Renault Logan, Toyota Corolla and a number of other models of various brands.
Troubleshooting the cigarette lighter and radio
The main list of factors that can immediately damage the radio and cigarette lighter on this Lada model is as follows:
- wire short circuit;
- loss of contact on the safety block;
- blown backlight bulb or fuse;
- oxidation or disconnection of contacts from long-term use.
In principle, any of the listed problems can be solved on your own, without resorting to the help of services or specialists. A number of simple manipulations that take no more than 15 minutes are sufficient in the vast majority of cases.
So, first you need to take care of checking the safety block, for which you need to remove it from the cavity under the hatch to the left of the steering wheel. On this block, you need to find the fuse numbered F4 and evaluate its external condition - at this stage, sometimes you can already see the malfunction.
If the fuse for the VAZ 2114 radio looks intact, you will have to remove it from the block and test it for functionality with any multimeter, tester or simple test screwdriver.
If a malfunction is detected, the part should be replaced with a new one - they are inexpensive and are sold everywhere.
In addition to the described operation, you need to be prepared to carry out the following procedures with the electrical network if the VAZ 2114 radio does not work:
- Assess the conductivity of the contacts with a tester.
- Tighten loose terminals.
- Re-clean or resolder faulty contacts.
- Make sure that the control lamp in the contact network is in working condition.
Returning to the analysis of common causes of breakdown, we can also advise checking the condition of the cigarette lighter socket itself, which could become loose due to vibrations, and its heating coil could become disconnected from the contact. Usually this unit is also replaced as an assembly due to its low cost.
Car cigarette lighter
The socket of this device can be used to connect non-standard equipment:
- phone chargers;
- laptops (tablets);
- compressors;
- vacuum cleaners;
- and so on.
In general, any household appliance that has a special adapter for connecting to the cigarette lighter socket.
The main disadvantage of this gadget is its unreliability in providing a long-term electrical connection. And also, switching high currents. The design features of the socket and the car cigarette lighter itself do not allow them to be kept in close contact with each other. As a result, due to vibrations of the car while driving, frequent disconnection (connection) of contacts occurs. Which leads to sparking of connections and in some cases can cause a short circuit. The same applies to adapter devices for connecting auxiliary household appliances.
Analysis of the operation of interior electrical appliances
On the VAZ 2114, as on other cars, the cigarette lighter is one of the weak points in the operation of the entire interior electrical network, for which there are a number of reasons.
The first is the demand for this device - anything can be connected to it, from a gadget charger to a vacuum cleaner. The problem becomes even more urgent if we consider that splitters are often connected to the cigarette lighter with the parallel use of several current consumers.
The second reason lies in the mechanical unreliability of this unit, which over time becomes loose due to loads and shaking, losing the tightness of the connection.
Cigarette lighter connection
Often the cigarette lighter and radio of the VAZ 2114 do not work due to the connection of devices to the connector that exceed its rated power values.
To understand why both options failed at once, you need to read the car’s instructions, which will indicate that not only the audio system and the cigarette lighter, but also the interior heater and heated rear window are connected to the same power circuit with a common fuse.
Consequently, an open circuit, short circuit or other breakdown of one of the devices can lead to the failure of others in the network.
Checking fuses
As a rule, replacing this fuse is enough to restore the function of all the listed devices, but if everything works, except for the tape recorder, you need to pay attention to the additional fuse of the VAZ 2114 radio, which is responsible for a separate audio device.
Replacing the fuse
The price of fuses and relays is usually no more than several tens or hundreds of rubles. It's worth keeping a few in reserve in the trunk of your car. The fuse replacement process includes the main steps:
- open the hood and find the fuse box (it is located between the engine compartment and the windshield);
- Using a special circuit located on the back of the plastic cover, we find the failed component;
- Using plastic tweezers or another dielectric tool, remove the fuse and install a new one.
It is worth noting that the replacement process is difficult - no special skills are required. But it is advisable to study all the notations in advance to avoid mistakes.
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).
VAZ 2115 fuse diagram: even a child can figure it out
Much has been said about the importance of such a small component of automotive wiring as a fuse. Indeed, the smallest part made of fusible metal, which melts and breaks the circuit when the permissible values are exceeded, can protect the car from short circuits, local power surges, and even fire. And besides, even a small child can actually figure out the VAZ 2115 fuse diagram
And besides, even a small child can actually figure out the VAZ 2115 fuse diagram.
What does a car enthusiast do if his beloved “iron horse” suddenly stops responding to individual orders? The windshield wipers or power windows suddenly stop working. What to do? Change the motor, and maybe the entire element, so to speak, as a whole? In fact, the first thing you should check is the fuses. It may well be that the whole problem is a spare part, the cost of which is comparable to a ticket for a city regular bus.
Location of relays and fuses in the mounting block: K1 – relay for turning on the headlight cleaners; K2 – relay-interrupter for direction indicators and hazard warning lights; K3 – Windshield wiper relay; K4 – lamp health monitoring relay; K5 – power window relay; K6 – relay for turning on sound signals; K7 – relay for turning on the heated rear window; K8 – headlight high beam relay; K9 – relay for low beam headlights; F1-F20 – fuses
Of course, replacing fuses only takes a professional a couple of minutes. However, you still need to get to a specialist. What if the ignition doesn't work? Order a tow truck? Expenses, expenses. But often it is enough to check the functionality of the fuses responsible for a particular block and spend the same five minutes replacing them. And your car will be like new again, and a visit to the service station can be postponed until there are really serious breakdowns.
The fuse box in the VAZ 2115 is hidden under the hood, on the driver's side. By opening the cover (it is secured with two simple latches), you get access to the fuses themselves and special tweezers, which are stored right there in the mounting block. It is very easy to decipher the designations of the relays and fuses located in the mounting block, especially if you have a diagram at hand. Relays are designated by the letter “K”, fuses by the letter “F”, the number allows you to determine the area of responsibility of a given fuse or relay; the value in “A” (amps) means the maximum voltage level for this fuse. So, next to fuse F2, which is responsible for the turn signals and the operation of the hazard warning lights, a level of 10A is indicated, that is, this is the load the fuse can withstand. Excessive voltage will damage the fuse, but will preserve the integrity of the system itself.

How to use a cigarette lighter so that it works for a long time
If you use your cigarette lighter correctly, you will maintain its usability for a long time.
First of all, you should not connect to it powerful consumers such as a compressor, which many now use to inflate wheels or blow air into the power unit. It is more correct to power this device through a rechargeable battery.
In this way, you will protect the wiring and fuses from overloads, and, therefore, they will not overheat, burn out or melt. Some craftsmen install a separate socket in the car for such devices - this is very forward-thinking and effective.
Also try not to stick adapters into the VAZ socket if it turns out that they are too thick - this will quickly break the core, which is made of ceramic.
