Where is the fuse for the VAZ-2114 radio and which one is responsible for the music in model 2115

Operating principle, design and characteristics of fuses

A protective device of this type consists of a housing, which is usually made of high-strength ceramics or special glass, and a fusible insert made of a conductive metal or alloy.

The body performs several functions:

• a fuse-link is built into it in a special way so that when the rated current of the insert is exceeded, it melts or breaks;
• the working thread is inserted into the chamber to extinguish the electric arc that occurs when the circuit breaks; this chamber is equipped in the housing;
• on the body, in those places and in the form as provided for by the fuse design, there are working contacts through which it must be connected to the general network.

Information about the characteristics of this protective device is printed on the housing. This is the rated current of the fuse link and the rated current of the fuse body at which it breaks.

According to their performance characteristics, these protective elements are divided into:

• fast-acting;
• low voltage;
• designed for medium voltage;
• manufactured for high voltages.

In automotive networks, the first two types are used.

The defining point showing the purpose of a particular protective device with a fuse link is its current characteristics. It is she who speaks about the range in which this element is ready to work.

1. To protect electric motors, fuses are installed whose inserts can withstand the rated current and its excess for a sufficiently long time necessary to start the main mechanism and reach its operating range. As a rule, such chargers (protective devices) are marked - g - as devices ready for protection from both overload and short circuit.
2. There are protective devices that operate effectively during short circuits and protect all equipment from very high voltage currents. Such chargers are marked - a - for protection only against short circuits.

Fuses for cars have several versions:

• low-current inserts, in networks up to 20 A, made of glass with a thin wire insert, there are ceramic cases, the ends are made of metal;
• fork inserts, most commonly used in vehicles, come in miniature and regular types.

According to GOST, a painting system for fusible chargers has been adopted depending on the rated current of the insert. 2 A - gray, 4 A - pink, 5 A - orange-yellow, 7.5 A - brown, 10 A - red, 15 A - blue, 20 A - yellow, 25 A - white, 30 A - green.

VAZ 2114 fuse box

On cars of the Samara 2 series, which include the VAZ 2114, there is a mounting block that is installed in the engine compartment under the windshield on the left side.

Location of the fuse box on the VAZ 2114

It houses various relays and fuses. Because of this, it is often called the fuse box. The cover of the mounting block is secured with clips made of plastic; they snap off quite easily and it is removed. On its inner side there is a diagram of the VAZ 2114 fuses. The rated current strength that is allowed in the circuit for each protective device is indicated there.

You cannot install a charger with a current exceeding the rated values ​​indicated in the diagram. In this case, damage to the electrical device located in the circuit is possible.

On injection machines, the relays and chargers are located as follows.

Purpose of fuses

What fuses are on the VAZ 2114? The electrical circuit of this car is designed in such a way that in front of all the main electrical units there are chargers located in the fuse box.

Replacing fuses on a VAZ 2114

When any problems are detected in the operation of the car’s electrical network and engine, be it the burnout of light bulbs or the failure of some electrical devices, the driver must first check the functionality of the fuses. The procedure is as follows:

• determine where the fuses are located on the VAZ 2114, which may have failed. To do this, look in the machine’s operating manual for a diagram of the location of the protective devices and determine whether they are located in the mounting block or under the dashboard in the area where the front passenger’s feet are located;
• when working with the car's electrical system, the negative contact of the battery must be disconnected;
• open the plastic latches holding the mounting block cover;
• remove the plastic tweezers from the mount in the upper right part of the block; they can be red, transparent or yellow;
• take the protective device, the circuit of which is supposed to be broken, by the body with tweezers and pull out the fuse;

• There are rules, developed by operating experience, on how to check the fuse. First of all, it is necessary to visually determine whether the fuse-link inside the case has burned out or whether the charger is in good condition;

• if the destruction of the insert cannot be visually determined, it is necessary to check the protective device using a device;
• If confirmation is received that the fuse has blown, it must be replaced with a functional one. The price for a VAZ 2114 fuse box on the automotive market is about 2,000 rubles, and a set of separate chargers of this type will cost 150 -250 rubles.

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.

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).

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.

The relationship between a car lighter and a radio in VAZ cars

A common problem for all VAZ car models (2114,2115, 2109, 2110, 21099), this is the same voltage supply circuit to the car player, with output to one common fuse, which is additionally responsible for the power supply:

• cabin heater (stove);
• cigarette lighter;
• heated rear window;
• the radio itself.

Thus, a failure as a result of a break, short circuit, etc., in the electrical circuit of any device leads to the shutdown of the rest.

Since the tape recorder is equipped with an additional safety device, coming after the main one, after checking them and replacing them, if necessary, the operation of the head unit, like all the above-mentioned equipment, is restored. If only the cigarette lighter (without the player) resumes operation, the cause of the malfunction should be sought in the car radio itself (which is the topic of a separate article).

Which fuse is responsible for the VAZ 2114 radio?

Some VAZ-2114 owners encountered such an inexplicable phenomenon when the radio and cigarette lighter stopped working at once. Naturally, the connection is smooth, although it is not even immediately visible. But how to find the nature of the malfunction, and of course remove it at home.

Structurally, the situation is such that the contact strips of the radio and the cigarette lighter are in the same branch, therefore, based on practice, if one does not work, then the second should not work.

And since this is AvtoVAZ, there is nothing surprising here and a problem can appear quite often.

The connection between the radio and the cigarette lighter in the design is very smooth. So, several electronic devices are connected to one branch of the electronic circuit at once and, in addition to those already indicated, the heated rear window and the interior heater can be connected.

The dismantled mounting block from the car.

Since the radio and cigarette lighter are electronic devices and are fed into one branch of the on-board network, then, most likely, faults need to be found specifically in the electronic part.

The main reason for the malfunction is a fuse that cannot withstand the load that the user brings to this address. Thus, connecting additional devices causes a short circuit, which will become a prerequisite for the fuse to burn out. However, based on practice, these are not all the tasks that will be associated with a non-working radio and cigarette lighter.

What is needed, let’s look at what other prerequisites arise as a result of operation:

• Connecting contacts to the safety group.
• Oxidation of contacts.
• Broken wire.
• Short closure.
• Backlight bulb burnout.

Now that the main prerequisites have been sorted out, we can move on specifically to methods of elimination.

The radio doesn't work

It is worth warning that if a motorist does not understand the design or is not sure that he will be able to repair the fault without the help of others, then it is recommended to refer it to experts at a car service center.

What is needed, let’s look at what methods there are to fight snowballs with a malfunction.

The most common cause of malfunction, or inoperability of the electrical circuit of individual parts, is a bad fuse.

Here you need to find the reason first.

The fuse box socket – F4 – is responsible for the radio and cigarette lighter. The marking of the fuse in a personal computer is preferably 20A.

However, not often and it can withstand the load placed there. Thus, the frequent and enormous introduction of additional devices leads to frequent burnout of this element. To check, it is worth pulling out and inspecting the fuse itself. As necessary, the element is changed to new ones; if you have anything left to do, our client has earned it, then the reason has been found. However, if the problem does not go away, then it is worth looking for it in other places.

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, as it is also called in the circuit, the wire blocks oxidize or burn out, and molten plastic can break the contacts.

To troubleshoot the problem, our client needs to check the contact blocks of the wires that go from the radio and cigarette lighter to the fuse box. What is needed, specifically oxidation and missing contact leads to inoperability of parts.

The next prerequisite is a break in the power wires. So, in order to find and remove the fault, you will need a tester, which will ring the wiring and find a broken wire . It is recommended not to fasten the wire with the old “old-fashioned method” of using electrical tape, but to replace it with a new one. This won’t take much time, so it’s better to do everything possible so that you get a short circuit and get into huge troubles.

Place of frequent malfunction of the cigarette lighter socket.

The worst thing that appears is a short circuit. The reason for this phenomenon is that frequent use of the cigarette lighter loosens the socket, causing the contacts to cross and cause a short circuit.

The standard cigarette lighter is simply a failure of the VAZ-2114.

Here, fixing the problem is quite easy - changing the socket. But, often motorists take a poor and affordable product, which repeats the function after a short time.

The backlight bulb is located in the same electrical circuit, so the burnout of this element becomes a prerequisite for a malfunction of the radio and the cigarette lighter at once. So, if you change the element, there is an option to improve the situation.

It’s quite easy to find a problem with the cigarette lighter and radio at once. Often, based on practice, the problem is hidden in the fuse or contact group; alas, we should not forget that there will be other prerequisites. Removing tasks is quite easy; if the motorist is not able to do this himself, it is worth contacting a car service center.

Causes of car cigarette lighter malfunction

Returning to our main topic, namely, why the cigarette lighter and radio do not work on the 2114 and other models, we list the possible causes of malfunctions:

• the safety device has burnt out;
• contact is broken in the fuse block;
• contacts have oxidized or burned due to frequent voltage surges during operation;
• the backlight burnt out;
• short circuit.

Private situations

General signs do not always indicate specific breakdowns. There may be exceptions. If individual devices refuse to work, it is quite possible that this is their personal problem. You'll have to parse the specific pointer. It may have a cracked gear that needs to be replaced.

Also, why doesn’t the instrument panel of the VAZ 2114 work? If the fuel gauge and tachometer are capricious (either they function, or they don’t react at all), the contacts and the mounting block are normal - you need to do a small check.

Reset is pressed and held, and the ignition is turned on at the same time. Raised arrows indicate the need for further searches. Lifeless - that microcracks have appeared in the shield itself. You will have to remove it and examine all soldering and traces under a magnifying glass. In principle, these are all the main options. If calling all the listed components and parts did not lead to the revival of the instrument panel, your case is individual, and you will have to determine the situation in the company of an experienced auto mechanic.

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.

1. 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.
2. Check the conductivity of the contacts with a probe. If they are loose, tighten them.
3. 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.

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

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.

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.

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.

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.

Finding a problem with both the cigarette lighter and the radio is quite simple. Often, as practice shows, the problem is hidden in the fuse or contact group, but do not forget that there may be other reasons. Fixing the problems is quite simple, but if the motorist cannot do this himself, it is worth contacting a car service center.
