The most common reason for the loss of the reverse light on a VAZ-2107 is oxidation and poor contact on the sensor switch located on the gearbox in the rear right part.
Due to the fact that the terminal chips are not structurally protected from the effects of water and salts from the road, they corrode, as a result of which contact with the sensor is broken and current stops flowing to the lamp lamps.
Also, the wires are not protected in any way from mechanical damage and the effects of road sandblasting. In our case, in addition to the oxidation of the contacts themselves on the sensor and wires, one of them broke.
Reversing lights are generally not a legal requirement, but they are useful. They serve two main purposes - to warn other road users that you are about to reverse, and to illuminate if you are reversing at night. The circuit is a simple mechanism consisting of one or two rear lights, which are activated using a switch. So if something goes wrong and you find that the reversing lights are not on, it will be quite easy to identify the cause of the failure.
On most cars, the switch is installed on the transmission, and it operates automatically when reverse is engaged. If you or the previous owner of the car made your own adjustments by adding lights yourself, the reverse lights can light up manually. In this case, the switch is most often installed on the dashboard, closer to the driver.

Checking the reverse light switch on a VAZ 2107
1. We install the VAZ 2107 car on an inspection hole or overpass (see “Preparation of the VAZ 2107 car for maintenance and repair”). 2. We clean the place where the reverse switch is attached and the switch itself from dirt. 3. Disconnect the wire blocks from the reverse switch terminals.
4. We turn on the reverse gear on the VAZ 2107 car. We connect an ohmmeter to the terminals of the reverse switch.
If the resistance tends to infinity, the reverse light switch on the VAZ 2107 is faulty.
Removing the reverse light switch from a VAZ 2107 car
1. Using a 27 mm spanner, unscrew the reverse switch.
2. Remove the reverse light switch. The connection between the switch and the gearbox is sealed with a copper washer.
Installing a reversing light switch on a VAZ 2107 car
1. Replace the sealing washer. 2. Installation of the reversing light switch is performed in the reverse order. 3. After connecting the wires to the terminals of the reverse switch, apply grease to them to protect them from water and dirt.

Checking the electrical wiring
If the current does not reach the lamp socket, you should check the rest of the electrical circuit in reverse order.
- Check your repair manual for the color and route of the reversing wires.
- Probe each wire along its entire length.
- In most cases the wire will disappear into the cable where you can't reach it.
- In this case, you should be extremely careful, because you risk damaging the working wire.
- Once you have identified the faulty section of the wire, remove it and install a piece of new wire in its place.
Important! Be sure to provide high-quality insulation at the wire connection points. The quality of the insulation primarily determines the reliability of the contact and the safety of the driver. You can also eliminate the possibility of a short circuit.
Video - Reverse gear does not light up on VAZ 2108, 2109, 21099. We are looking for the reason
The design of VAZ 2107 cars has a light alarm that indicates that the car is moving in reverse. This is one of the main indicators by which accidents can be prevented. The operation of this light alarm depends on the functionality of the sensor. However, situations often arise when the VAZ 2107 reverse sensor fails, which leads to the need for immediate repairs.
Why the reverse light doesn't light up - common reasons
These lighting devices, in principle, like all others that have at least some connection with the electrical part, quite often fail during the operation of the car. And there are many reasons for this; it makes no sense to consider each of them. Therefore, we will try to analyze the most common of them.
Device of a warning system about a change in direction of a car
The main reasons for failure of reverse lights:
- the light bulbs are burnt out;
- fuses have failed;
- contacts have oxidized;
- The reverse sensor has failed;
- there was a break in the electrical circuit.
In order to identify the cause of the malfunction and eliminate it as quickly and efficiently as possible, we will consider each option separately.
Dimensions of VAZ 2104, 2105, 2107 do not light up
On VAZ 2104, 2105, 2107 cars there are 4 side lights (dimensions): one in the front headlights and one in the rear lights.
Failure of any of them to work is a fairly common occurrence. Let's look at the reasons for this malfunction - “why the lights on VAZ 2104, 2105, 2107 cars don’t light up.”
Symptoms of a malfunction: “VAZ 2104, 2105, 2107 dimensions do not light up”
One dimension, two dimensions (front or rear, right or left side, crosswise) or all of them may not work.
Causes of the malfunction “dimensions of VAZ 2104, 2105, 2107 cars do not light up”
The side light bulb is burnt out
The most common reason. One light bulb, or several at once, can suddenly burn out. In some cases, it may be impossible to visually identify a burnt-out light bulb. Therefore, we replace the burnt out one with a known good one. You can use a similar one from a nearby headlight.
The contacts of the light bulb in the socket have oxidized
We rotate the light bulb in the socket several times to remove the oxidized layer and restore contact. In the future, you can clean everything with sandpaper.
Lost ground to headlights or taillights
Loss of contact with ground leads to failure of not only one size, but also the entire headlight or rear light.
The “negative” wires of the front headlights and rear lights with side lights on VAZ 2104, 2105, 2107 cars are attached to the car body. It is necessary to clean the mounting location to ensure good contact with ground. Usually the negative wire is the black wire from the headlight connection block, attached to the body next to the headlight or tail light.
Broken contact in the headlight or rear light connection block
Either it has oxidized or the block is not attached tightly. In such a situation, either one side lamp or the entire headlight may not light. We put on and take off the pad several times to restore contact.
The track in the rear light board has crumbled
During long-term use of the vehicle, or if a low-quality part is installed, the track to the side light lamp socket in the rear lights may shed (burn out).
Contact is broken in the connecting blocks of the relay and fuse mounting block
Check the pads Ш12 (Х12), Ш13 (Х13), Ш9 (Х9), Ш6 (Х6) of the mounting block. Or Ш2 (Х2) - terminals 1 and 3 if all the dimensions do not light up.
The fuse in the mounting block has blown
If fuse No. 14 (F14) is blown, the side lights in the front left headlight and rear right headlight will not light. If No. 15 (F15), then the marker in the front right headlight and rear left lamp will not light up, that is, crosswise.
The fuses must be replaced with serviceable ones and the cause of their burnout must be determined in the future. There may be a short circuit in the electrical circuit.
The external lighting switch on the instrument panel is faulty
All dimensions will not light up. Remove the switch and remove the wire block from it. Connect the leads of the black and yellow-red wires with a piece of wire. Turn on the ignition. If the dimensions light up, the switch is faulty and must be replaced.
“Open” in the electrical circuit connecting the side lights
It is necessary to check the sections of the circuit responsible for the non-burning light using the connection diagram. Read more: “How to find an open circuit in a car’s electrical circuit.”

parking lights
Dimensions on the VAZ-2107 are activated by the leftmost of the four key switches located under the gearbox control lever . This switch is a three-position switch: the side light, along with the license plate light and instrument lighting, is turned on in the second position.
The side lights are activated by a three-position switch located under the gearshift lever.
On the fuse block, which is located under the hood of the car near the windshield closer to the passenger seat, the rear side lights fuses are numbered F14 (8A/10A) and F15 (8A/10A). In this case, fuse F14 is responsible for the operation of the side lights of the left front headlight and the right rear light, as well as:
- a lamp indicating the operation of the dimensions;
- license plate lights;
- engine compartment light bulbs.
Fuse F15 is installed in the side light circuit of the right headlight and left rear light, as well as:
- instrument lighting;
- cigarette lighter lamps;
- glove compartment lighting.
If one of these lamps does not work, you should check the integrity of fuses F14 and F15.

Do-it-yourself IAC replacement
The IAC needs to be cleaned, and if that doesn’t help, then change it. If it is necessary to replace the idle speed sensor of a VAZ 2107, then even a novice car enthusiast can cope with this procedure.
Tools and materials
For the procedure you will need the following tools:
- socket wrench set to “13”;
- Phillips and flathead screwdrivers;
- tape clamps for pipes;
- pad.
To check the functionality of the regulator, you will need a voltmeter. The IAC is located on the throttle valve. The voltage is measured at the contacts. If it is below 12 V, then there is a malfunction in the control unit or in the power circuit. If the voltage is 12 V, then the regulator is faulty.

Stages
The idle speed regulator on the VAZ 2107, located on the DZ, changes along with its body.
The procedure itself consists of the following steps:
- First of all, the car is de-energized by disconnecting the negative terminal on the battery.
- Next, you need to disconnect the cable with which the remote control is controlled.
- Next, you need to disconnect the wire block from the TPS and from the IAC.
- We loosen the clamps on the coolant inlet and outlet pipes, and disconnect them from the control valve.
- After loosening the clamp, disconnect the crankcase ventilation pipe.
- Next, you need to loosen the clamp on the hose that supplies fuel vapor to the remote control and disconnect the hose.
- After unscrewing the fastening nuts, remove the DZ housing from the studs and take out the gasket.
- Next, unscrew the fastening bolts and remove the IAC.
- On the removed regulator, check the O-ring; if it is worn out, replace it.
- Then we check the IAC voltage at the terminals of its windings. Between outputs AC and BD it should be infinite, between AB and CD - about 53 Ohms. If the readings are not the same, the device needs to be changed.
- Before installing a new IAC, you need to check that the needle does not protrude more than 23 mm, otherwise we replace the valve with a new one.
- Before replacing the device, lubricate the seal with engine oil.
- Installation of the DXX is carried out in the reverse order.
Thus, replacing the idle speed sensor on a VAZ 2107 is completed (video author - Ovsiuk).
Tail lights of VAZ-2107: operating and maintenance rules
Tail lights occupy a special place in the car lighting system due to their functional purpose and ability to change the appearance of the car using tuning. Safety on the road largely depends on the performance of the rear lights, since it is from the light devices located in the rear of the car that drivers of vehicles behind can understand what maneuver the driver of the car in front intends to take. The rear lights of the VAZ 2107 have their own characteristics that must be taken into account when operating and maintaining the vehicle.
How does the reverse sensor work on a VAZ seven?
Any limit switch is a switch and a mechanical drive of a contact group. The “seven” version uses not a rod, but a ball pressed into the body. The stroke is small, good tightness is ensured. A design flaw is that there is little space for the contact group to move freely. If the contacts wear out, the clamping force may not be enough.
The advantage is ease of manufacture, absence of rod seals and compactness. In addition, the sensor installed on the VAZ 2107 ensures the tightness of the gearbox even if it breaks down.
There is no point in listing the signs of a malfunction: except for turning on the rear lights, the sensor no longer performs any tasks. In addition, the reason is not necessarily in the trailer itself.
Stop signal
The brake light switch is located on the brake pedal hanger holder . The brake light is turned on as follows: when you press the brake pedal, the spring in the switch presses the control pin. At the same time, the contacts in the switch close the brake light circuit. When the brake pedal is released, the pin returns to its original position and the brake light goes off.
If the brake lights do not work on a VAZ-2107, you should make sure that the cause of the malfunction is not in the switch. To do this, you need to unscrew the ends of the power wires and place a jumper between them: if the brake lights turn on, the switch should be repaired or replaced. To replace the brake light switch, you must turn it clockwise 90 degrees and remove it from the mount. After installing the new switch, make sure that the neck of the switch fits snugly against the brake pedal and turn it 90 degrees counterclockwise. The new switch is adjusted automatically when the brake pedal is pressed. The switch operates normally if the brake light is turned on no earlier than the brake pedal has been moved 5 mm, but no later than it has been pressed 20 mm.
Fuse F11 is installed in the brake light circuit, which, in addition, is responsible for the operation of the interior body lighting.
Some VAZ-2107 owners install an additional brake light so that the signals given by the driver are more visible on the road. This type of brake light is usually placed on the rear window inside the cabin and operates on LEDs.
To enhance the “visibility” of the car on the road, an additional brake light can be installed
Troubleshooting procedure
Lamps fail most often. It's best to start with them. If they are working properly, remove the plugs from the frog and connect them together. The plugs should have +12.

The fuse box can only be repaired in specialized workshops. In this case, the board track could have burned out.
It is extremely rare for the brake light wire to break. The wiring harness comes out from under the instrument panel and runs along the floor of the car under the carpet. Both brake lights are connected in parallel. We check the integrity of the wire from the frog to the lights. If necessary, replace a separate stop wire.

Reversing light
A reversing light is not mandatory, however, its use can significantly increase the safety of the car. This light device is activated when reverse gear is engaged and performs the following functions:
- illumination of a section of the road and objects located behind the car when reversing in the dark;
- informing other road users that the vehicle is moving in reverse.
The principle of operation of the reversing light is based on the closure of the electrical circuit into which the reversing lamps are connected when the ignition and reverse gear are turned on. The closure occurs using the so-called “frog” installed on the gearbox.
Fuse F1 is connected to the reversing light circuit, which is also responsible for the heater motor, rear window cleaner and washer.
Fuses
In many cases, the fuse protects the reversing lamps and also covers other accessories. If this does not give a positive result, replace the fuse and test again. If after replacement the new fuse melts again, then this indicates a short circuit that has occurred somewhere in the circuit. In this case, you should contact an electrician who can quickly determine the location of the short circuit in the electrical circuit.
If the other fused components are still working, then you need to check the rest of the circuit using a test light.

You can find an article about this here. You may also be interested in our new article on the topic “How to adjust the clutch.”
Main reasons
- The fuse has blown. Both lamp bulbs are protected by one fuse link. Along with the lamps, the fuse will most likely protect some other circuits. Therefore, if on your car not only the rear lights do not start to glow, but, for example, the dashboard backlight does not work, you first need to check the fuse. You can find out which “socket” in the mounting block the lamp circuit goes through from the repair and operation department of your car. In almost all cases, the main circuits are shown graphically on the inside of the fuse box cover.
- Limit switch faulty.
- Open circuit (breaking pins in connectors, chafing of wires).
- Formation of oxides, corrosion at the junctions of contacts, burning of pins.
- Poor ground contact of the lights. In case of problems with the total “mass”, brake lights and turn signals may also NOT work. It is very unlikely that both bulbs stopped glowing in an instant due to problems with the contact in the flashlight. But a bad ground may be the reason why the reverse gear light does not light up on only one side. Obviously, in this case it is worth checking the lamp itself.
Checking the circuit
The essence of diagnosing the reason why the reverse lights do not work comes down to identifying the section of the circuit where the voltage is lost. To do this, you can use an ordinary control lamp. Checking the continuity of the circuit is carried out with an ohmmeter, so you should know how to use a multimeter.
You can start checking specifically with the limit switch connector. Turn on the ignition. Connect one contact of the control light to the unpainted iron part in contact with the body, and the 2nd. to the "" connector.
- If power comes in, check the reverse sensor.
- If, after installing the “jumper” in the connector, the light bulbs do not glow, it means there is a problem in the section of the wire circuit going from the connector to the lamp. Ring the wire to the point where it divides into light bulbs on the left and right sides. Most likely, the reason is specifically the break.
To find the pinout of connectors, light contacts, and wire colors, be sure to study the electrical diagram of your model and vehicle configuration.
How to manually unlock the hatch door of a washing machine?
The most accurate scheme for unlocking your washing machine is in the instructions. But if the treasured document is lost somewhere on the shelves, try using the standard scheme:
- First, if you haven’t already done so, unplug the washing machine
. - Secondly, open the small hatch on the front panel (drain filter) and check if your unit has an emergency hatch release cable
. It is usually orange in color. If there is a cable, then you need to carefully pull it, and the hatch door will unlock. - If the cable is not in the indicated place, then to forcibly unlock the hatch you will have to remove the top panel
, then tilt the car back so that the drum, under its weight, also moves a little away from the front wall and frees up room for you to maneuver. Next, you need to reach the lock, by touchfind the latch and move it to the side
.
Note! If you are not sure that you can unlock the door yourself, entrust this work to a specialist!

The design of washing machines is designed in such a way that the door opens easily. However, there are times when errors or malfunctions occur due to which the washing machine does not open. What to do, and will you be able to cope with such a difficulty on your own? This is exactly what we will talk about next.
Tuning the rear lights of the VAZ-2107
You can add exclusivity to your “Seven” using one of the taillight tuning options available today. You can modify the rear lights using:
- use of LEDs;
- applying a tinting layer;
- installation of alternative lights.
Tinting of lamps is done with film or special varnish . Unlike tinting the headlights, for which you can get a fine, in this case the state traffic inspectorate usually has no questions about the rear lights. The main thing is that the color of all signals complies with the requirements of the traffic police: clearance and brake lights must be red, direction indicators must be orange, and the reversing light must be white.
I don’t know about anyone else - but my question was about the reflector - it clearly interferes with this device! I advise you to try this on an old taillight, using plexiglass instead of the stock one! That is, the glass of the rear light is replaced with plexiglass - but here LEDs are already asking for the headbands, and the feet, and the clearance - everything is done experimentally!
