VAZ 2110 cigarette lighter fuse and relay: how to remove and replace

Almost all car owners, including non-smokers, use this device. The cigarette lighter socket is used as a 12-volt socket for connecting various electrical devices:

fan;
compressor;
navigator;
DVR;
charger for phone or laptop.

VAZ 2110 models are equipped with long, old-style cigarette lighters. Their disadvantage is that they do not provide reliable fixation of connected devices that are designed to meet European standards. As a result, the devices sometimes short out and refuse to work correctly, causing the fuse to trip. Some owners decide to replace the cigarette lighter with Euro standards in the VAZ 2110. The following are instructions on how to change the device to a short one with your own hands without the help of a specialist, and install a new fuse.

Required Tools

Before dismantling the cigarette lighter on a VAZ 2110, repairing it or installing a new device, or replacing a fuse, you will need to stock up on suitable devices. To work you will need:

Phillips and standard screwdriver;
protective gloves.

To fix a broken cigarette lighter or fuse, the following will be useful:

multitester;
blowtorch with solder;
heat shrink tubes, electrical tape;
wire cutters;
needle file

Nuances

There are several ways to extend the life of a new cigarette lighter. If you do not follow these tips, you will be changing this device regularly. Here are the most important points:

The most important thing is not to allow the current consumption to exceed. In the case when you connect tees to the cigarette lighter, most likely you will simply ruin it. The cigarette lighter is not designed for such loads. Never connect several devices to it at the same time;
It is also worth choosing fuses carefully. They only look completely identical. In fact, they may differ slightly from one manufacturer to another. But even a difference of half an ampere can be critical. Therefore, purchase fuses only from proven brands;
If
a fuse is blown, it is worth checking all the wiring that touches it. Often it is also damaged, and subsequently it can affect the operation of the cigarette lighter, or cause the fuse to re-blow.

Why did the cigarette lighter break?

Over time, the device may stop working. The most common reasons why a VAZ cigarette lighter breaks.

Blown fuse. The element protects the circuit from wire melting or fire. If the maximum permissible current parameters are exceeded, the fuse fails. It is necessary to remove it from the mounting block. Fuse F18 should be replaced with a serviceable element with the same rating (25 amperes).
Cigarette lighter wiring broken or short circuited. If a car fuse burns frequently, it means there is a short in the circuit. This failure should be diagnosed using a multitester. The wires coming to the cigarette lighter are tested for resistance. The fuse blows.
Poor contact. Over time, the connector on the VAZ 2110 may become loose and the contacts may oxidize, not guaranteeing a good connection. The repair is simple - you need to remove the cigarette lighter from the socket, process the contact points with a file and bend them for better fixation of the device.
Burnt out spiral. The metal thread located inside the device on the VAZ 2110 can burn out due to frequent thermal exposure, and the fuse trips. It is worth replacing the cigarette lighter.
A burnt-out backlight bulb in a VAZ 2110. There is additional lighting around the device itself to help you find the device in the dark. Over time, the light bulb may also stop lighting and the fuse will trip. You will need to remove the burnt element and then replace it with a working one.

How does a cigarette lighter work?

The device system is quite simple. The principle of operation is as follows.

A spring-loaded lid with a filament extends into the interior. When it is pressed, the working element heats up. After sufficient heating, the key snaps out of the groove and the cigarette lighter cover rises. Then it can be removed and used for its intended purpose.

Checking the condition of the wiring and contacts

If the device does not work correctly or fails altogether, you should check the entire circuit, including protective elements. Typically, diagnostics are performed in the following sequence:

remove the dashboard;
find two wires connected to the cigarette lighter;
inspect the joints for damage, oxides, melting;
Next, you should follow the line to the fuse box and find the required fuse link and check its condition.

Let's summarize

Obviously, the procedure for replacing the cigarette lighter is quite simple, even a beginner can do it. But you need to understand that the cigarette lighter will have to be changed often if the current consumption increases above 25 amperes. Once this value is reached, the entire procedure described above will have to be performed again, since the node will inevitably fail. The most common reason for this is connecting multiple devices at the same time. You should not use tees, and you should always know exactly how much the device you want to connect to the cigarette lighter consumes. This will extend the life of both the unit itself and the fuses.

Maybe the fuse has blown?

Before removing and replacing the VAZ 2110 cigarette lighter, you should check the serviceability of the protective element. This is a fairly common failure. The car circuit in this area is protected by a 25 ampere 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 socket.

Otherwise, the fuse on the VAZ 2110 will blow out. A hint that it was he who “gave up” is the failure of the heater fan. If the device does not work, the fuse should be replaced. The location of the mounting block is to the left of the steering column, behind the decorative panel trim.

To make it easier to pull out the fuse, you should use tweezers. It is necessary to change the part with index F-18. The fuse rating is 25 amperes. It is prohibited to install parts designed to carry high current. An unsuitable fuse may result in a short circuit, damage to wiring cables, or fire.

Location of fuses on the diagram for VAZ 2110

The main unit is located behind a protective cover that protects it from moisture, dust and dirt. Location: near the left foot at the bottom of the dashboard. The main fuses and fusible links of the car are concentrated here. The console controls most of the car's electrical equipment.

There are also auxiliary blocks - one is located in the niche of the gearbox housing and contains mainly protective relays. It can be found behind the plastic cover on the left side of the front passenger footwell.

Which fuse is responsible for the cigarette lighter?

The car circuit has a number of fusible links responsible for protecting the on-board circuits. Insert F18 is responsible for the cigarette lighter device. The fuse has a rated limit of 25 Amps. It is quite easy to find the part in the main fuse box. She is located in the bottom row, third from the right.

Fuse blown

When such a breakdown occurs, the entire system stops working. Any manipulations of the car enthusiast remain without reaction or response. If the insert burns out, check the lines and contacts for short circuits. Only after eliminating the breakdown can you change the VAZ 2110 fuse.

Replacing the fuse

To change a burnt-out element, follow a simple procedure:

find the required insert;
carefully remove the damaged part from the socket;
inspect the nest for damage or burns;
insert the new fuse into the seat.

Important! It is strictly not recommended to pull out the fuse by swinging it - this can damage the socket or tear off the thin leg, which will cause even greater damage. For replacement, special forceps or tweezers are used.

What will you need?

It is worth paying attention to the need for proper selection of fuses. This requires 25A fuses

.
If you take a lower value, they will light up immediately after turning on the cigarette lighter. If you take a fuse with a higher rating, it simply will not work. There is a known case where the driver installed a 30A
. As a result, when he noticed the smell of burnt insulation, some of the wires going to the cigarette lighter were burned, and the fuse itself melted. More precisely, the plastic shell melted, but the conductor was intact and working.

Replacement with tunnel dismantling

According to the user manual, the device must be removed by removing the decorative cover of the central tunnel. The instructions will tell you how to correctly remove the cigarette lighter of the VAZ 2110.

Turn off the ignition, open the hood, remove the negative terminal.

The negative terminal is connected to the car body.
The plus filament is located in the center and is connected to the cigarette lighter power line coming out of the fuse box.
The third contact is intended to supply power from the vehicle's side lighting.

Important! The standard block 2110 is not suitable for working with the Euro module. To do this, just find a contact connector in any auto store.

How to correctly connect the cigarette lighter directly to the battery via a fuse

It is enough to perform a simple sequence of actions.

Route the power line to the battery under the hood.
Connect the line securely to the battery terminal.
Next you need to insert a fuse into the system. It is usually placed directly in front of the device.
It is also useful to install a switch or relay here. To be able to accurately control the activation and deactivation of equipment. Typically, users connect the relay to the ignition switch. Thus, only after turning the key in the cylinder, the device will be powered.
The final step is connecting the wiring to the device.

We drill a hole of a suitable diameter and clean the edges with a file.
We connect to the wiring, observing the polarity and passing them through the fuse.
We check the functionality of the model and carry out assembly.

Order of Operations

Before removing the cigarette lighter of a VAZ 2110, 2111 or 2112, you need to de-energize the circuit; to do this, remove the negative terminal from the battery. Now you can start working directly:

It is necessary to remove the plates on each side of the instrument tunnel; to do this, unscrew two bolts from each. On the right side, disconnect the backlight and cigarette lighter connector.
The housing of the unit is fixed to the casing of the instrument tunnel; it must be removed. The trim is located under the handbrake lever. It can be easily removed with a flat screwdriver.
Also, using a flat-head screwdriver, you now need to pry and remove the housing from the gearbox shift lever.
There is a screw under the cover; you need to unscrew it with a Phillips screwdriver.
Now the driver and front passenger seats need to be moved back and the gearbox screws unscrewed. There are five of them.
You need to remove the top cover of the instrument tunnel. Now the cigarette lighter is accessible. You can remove its cartridge. Then the screen is removed so that the tabs come out of the grooves on the light guide.
Use a flat-head screwdriver to press the latch next to the cigarette lighter socket, so it is released from the light guide.
Now you can remove the assembly along with all the elements.
Then you need to tighten the latches on the light guide, so it is immediately disconnected from the assembly.
If you need to change the LED itself, it can be easily removed by pressing the tabs on the housing. When installing a new device, make sure that the slot in the casing aligns with the protrusion on the housing.
Now you can begin installing the new cigarette lighter. First, it is connected to the light guide, the following operations are performed in the reverse order.

To replace the cigarette lighter of a VAZ 2110, 2111, 2112 with your own hands without disassembling the tunnel, watch the video:

On a note! If, when checking the fuses, it turns out that they are the ones that have failed, they need to be replaced with elements of the same brand. Units from various brands are on sale, and despite the fact that manufacturers claim the same technical characteristics, in reality everything turns out to be different.

The standard cigarette lighter of the VAZ 2110, 2111, 2112 does not allow the use of all devices existing on the market, so owners often replace it with a European-style unit. How to do this, watch the video:

How to connect the device to a cigarette lighter without a plug

Some owners decide to abandon the device itself and prefer to install other devices directly. To connect the device directly without a plug you will need:

blowtorch, solder;
screwdriver.

Procedure.

We dismantle the car cigarette lighter, gaining access to the cables.
We connect the wires of the installed device, observing the polarity.
We carry out the assembly.

Connection diagram.

A constant minus. Comes to the car body.
A constant plus. Connects through a fuse to the battery.
Plus, coming up to the backlight bulb.

Important points

Replacing the cigarette lighter is good, but the new device is unlikely to last long if the car owner does not follow a simple rule: do not allow the current consumption to exceed 25 amperes. As soon as the current exceeds this limit, the entire above procedure will have to be carried out again, because the cigarette lighter (or fuse) will inevitably be damaged. Most often this happens when the driver uses various tees, that is, connects several devices to the cigarette lighter socket at once. This should be avoided at all costs.
If the cigarette lighter remains intact, but only the fuse had to be replaced, it must be replaced with a device of the same brand. Auto parts stores today have a lot of fuses from various companies. Despite the fact that their passport characteristics are the same, in practice this is often not the case. And in the case of a cigarette lighter, an error of even half an ampere can be critical, and it will very quickly fail.

As can be seen from the above article, to replace the cigarette lighter you do not need to take the car to a car service center and even a novice car enthusiast can perform this operation. But it is important to remember that even the highest quality cigarette lighter is unlikely to last long if the owner has the habit of connecting everything to it at once. The best option here is to know exactly how much current a particular device connected to the cigarette lighter consumes. This knowledge will significantly extend the life of both the fuses and the device itself.

Cigarette lighter not from ignition

There is a way to connect directly to the car battery. This scheme has advantages: if you connect the cigarette lighter directly to the battery, you can avoid interfering with the wiring itself and the fuse. The work will take less time; the positive cables should be led directly to the battery, and the negative cables should be attached to the car body.

It is also important to remember that you need to select the right spare parts. Initially, this concerns the wires. Each square millimeter of cross-section is designed for 5-10 amperes of current. Should be taken with reserve. A cross-section of 3–5 mm is quite sufficient to transmit the required voltage. Otherwise, the wires may burn and the fuse will trip. This will result in a risk of short circuit. The circuit should be routed through an additional fuse with a rating specified by the manufacturer.

Basic faults

The most common problem is trying to connect several devices to the cigarette lighter at the same time. In this case, increased power consumption occurs, which the cigarette lighter is not designed for. As a result, several malfunctions may appear at once, which will lead to the failure of this device.

If you notice that the cigarette lighter is not working, you should first check the fuses. In many cases, when a large load is applied, they are the ones that cannot withstand. Therefore, diagnostics should begin with checking the mounting fuse block. The following fuses are responsible for the operation of the device:

F18
;
F6
.
