With what to begin inspection if the dimensions on VAZ 2109 do not burn? Lighting will always remain a painful topic, so this is a matter of security, especially during the movement. Everyone is pleased when all the bulbs burn in the car, the instrument panel is fully illuminated, and halogens and dipped lights are the maximum permissible illuminate the way.
In such cases, the ride becomes quiet, calm and relaxed, but how things change when at least one light bulb burns out. How much this brings inconveniences and emergency situations, besides, you can still get a fine from a road service employee.
Possible problems and solutions
Do not burn the dimensions of the VAZ 2109, then look for the reason in the wiring. Even experienced drivers recommend checking the efficiency of all devices and assemblies before going out. Not an exception there is also a nine, in which optics can often refuse for various reasons, among which:
- Breakage of the wire contact;
- The lamp burned out;
- The board burst.
- F10: responsible for light dimensions, both in front and behind, the backlight of the dashboard, cigarette lighter and license plate;
- F11: is fixed only to the right side of the rear dimension.
So, if the F10 burns out, it will be noticeable, since the entire instrument panel goes out, that's when the F11, then you will not notice the problem. For diagnostics, it is necessary to open the bonnet cover and find the required F11 in the mounting block.
In the event that everything is normal with the fuse, then we are looking for the marking K4 Is a lamp relay. Often it has the property of blowing. In the assembly block, it is easy to find it on a black circle with the multiplication symbol inside. old owners so as not to suffer, set metal jumpers.
Another characteristic cause, that the dimensions are too small, there can be banal oxidation of the terminals in the mounting block. I will explain why: it is structurally located in close proximity to the drain hole, so that in good rain or downpours it is possible to get water and leaves, which will lead to a short circuit. Just a matter of time and no more.
The rubber cover is not durable, which after a couple of years will lose its tightness, and the drain hole will be clogged with debris.
There are possible reasons for the damage to the wiring, but its solutions are strictly delineated: either to look for yourself, but on condition that you understand the essence of the matter or to the car service master. But the reason to eliminate all the same is necessary, as it is, first of all, our own safety and the safety of the passengers, which the driver is transporting.
If the car with age, there is a damage to the wiring throughout the body, due to natural aging and the negative effects of weather conditions. Negative temperatures lead to the fact that the winding loses its elastic functions and the wire simply breaks in half.
At any repair of the car, especially elements of an electric equipment and everything, that with it is connected, it is extremely desirable to remove a minus terminal from the accumulator. Otherwise, you can get into a completely confusing situation. For example, if the dimensions and lighting of the instruments on the Lacetti Chevrolet do not burn, a logical connection between them can not be traced. But this is only at first sight.
Why the dimensions and lighting of the instruments on the Chevrolet Lachetti
The instrument panel lights went out.
To begin with, we will find a connection between the dimensions and the illumination of the instruments.
Location of the fuse box.
Based on the scheme of electrical equipment Lachetti different years of production, for the parking lights is the fuse F6 nominal 10 A, and for the operation of the instrument panel - fuse F4 with the same value.
Guaranteed short circuit
Nevertheless, in 99% of cases it turns out that if the dimensions and illumination of the devices do not light up, the replacement of these fuses does not give anything and their test will show that they are all right.
In fact, no mysticism. In almost all cases, such a malfunction occurs immediately after installing the glove box, replacing its backlight or switch.
Attention. Before replacing the backlight of the glove compartment, be sure to remove the negative battery terminal, otherwise the instrument panel light may go out.
The fact is that if you do not remove the negative terminal from the battery and start disassembling the glove compartment, the short circuit in the glove compartment lighting circuit is guaranteed - the contacts of the cartridge will inevitably be closed to the ground, if not to de-energize the machine.
Even in the event that we did not take apart the glove compartment, but at the same time the overall lighting and the lighting of the instruments were lost, with a high degree of probability could reattach and close the wiring harness, leading to the switch and to the glove compartment lighting, which will also cause a short circuit and burnout of fuse F21. It is responsible for the rear fog lights.
If you do everything right, the dimensions will burn again.
Find the cause and restore the light
Rear fog light fuse.
And here the glove compartment and rear fog lights? The 15-amp fuse F21 is tied to the glove compartment lighting and the battery-saving mode module. If there is a short circuit in the circuit, this fuse blows out, which feeds the fuse of the main battery pack.
This fuse is marked ef1 (30 A rating) and installed in the mounting block under the hood of the car. In addition, it protects the circuits F13, F14, F15, F16, F21, F22, F23 and F24, and in these circuits just the parking lights and the backlight of the dashboard.
Check Algorithm for Chevrolet Lacetti
Therefore, to solve the problem, do the following:
- Check if the backlight glove box is working . If it does not work, we disassemble the glovebox (after removing the negative terminal with the battery), we call the power wires to the switch and to the bulb, if necessary, we search for an open or short circuit and eliminate the problem.
To begin with, we look at the glare of the glove box.
- Check the integrity of fuses F4 and F6 , they are on the left, at the front of the front panel in the cabin, in the salon mounting block. If necessary, replace them with the equivalent at par value (10 A).
We check the integrity of fuses F4 and F6.
- Check the integrity of the F21 fuse with a rating of 15 A , which according to the scheme is responsible for the operation of the rear fog lamps.
- Check the fuse EF1 at 30 A , which is installed in a sub-hood assembly unit, if necessary, replace it with a similar one.
Under the hood there is also a fuse box.
- Next, you need to get to the instrument panel and check the integrity of the lamps on it.
The back of the instrument panel.
- If all the fuses are whole and the lamps, too, but the problem is not solved, most likely, the case in the energy-saving module . Its catalog number - 96408390 , it is located in the engine compartment. The module breaks down extremely rarely, but it is possible.
conclusions
Thus, using the scheme of electrical equipment and logic, you can find the cause of non-working highlights and dimensions. Successful search and smooth sunny roads!
Side lights are bulbs that show other drivers your dimensions. For example, if you stopped on the roadside, the ignition and dipped beam can be turned off, into the parking lights continue to burn. If the dimensions do not light when stationary, this can be a fine and carries the risk of a traffic accident.
Why do not the dimensions burn?
If the bulb does not light up, the car needs an urgent inspection and troubleshooting.
The reasons can be the following:
- - Burnout of a light bulb. If only one dimension is missing, for example, the rear, first check the lamp and replace the burned one with a working one. In extreme cases, use a similar lamp from another lights.
- - Fuse blown. If the left dimensions on the front and rear cease to burn, the probable cause is hidden in the mounting block - in the fuse, which is responsible for the left dimensions, highlighting the interior, the number and the dashboard.
- - Oxidation of contacts. Inspect the fuse box. The reason can be in the oxidation, detachment and poor contact of the pads. To solve the problem, the contacts are cleaned and firmly connected.
- - Oxidation of contacts in the bulb of the lamp dimensions. To solve the problem 3-5 times turn the lamp in the cartridge, which will remove the oxidized layer and restore the contact. Sand the surface with sandpaper.
- - Failure of the power button. The reason, if the envelope is not lit, can be the malfunction of the light switch due to loss of contact or oxidation of the wire. You need to clean it, fix it and check it.
- - The fuse is on. The fuse can be permanently lit because of a weak contact in the unit or a short circuit. Take the 12 Watt light bulb and connect 2 wires to it. Remove the fuse and connect the wires from the lamp to its contact areas. If it caught fire, the cause of the fault is in the fault. To find out exactly where it is, turn off and check everything that this fuse is responsible for.
The most common causes for which the dimensions ceased to burn are listed. If after correcting the problem you can not correct the problem, contact the service center for inspection by qualified specialists.
