How is a relay different from a fuse?
Fuses are needed to break the circuit when the current increases above certain values. This is necessary in order to protect wires and electronic components from damage. A sharp increase in current is usually associated with a short circuit.
The Chevrolet Niva uses blade-type fuses.
Each of them corresponds to a certain current strength, which is critical for the circuit. When a short circuit occurs, the small jumper inside the fuse burns, thereby breaking the circuit.
That is why it is also called “fusible”. When replacing, you must always de-energize the circuit that it protects, and then install a new element.
The relay is an electronically controlled switch. Relays are often used to turn on elements remotely, so that there is no need to run a large number of cables to the instrument panel. Typically, a relay uses a lower current to operate than the circuit it controls. Some have a timer function, such as those used to control the windshield wiper or turn signal lamp. This allows you to set an impulse at certain intervals.
Most relays and fuses are located in the passenger compartment, in a special panel, on the driver's side. But specialized relays that control high-current wires are placed under the hood in the engine compartment.

Modern AvtoVAZ SUVs use injection power units. If a malfunction is detected in the electrical equipment of the car, you should first check the serviceability of the fuses and relays. Next, we will show where the mounting block is located (fuse box or black box), as well as the location of the elements inside it.
Location of fuse and relay blocks Lada 4×4
The main part of the fuses is located in the interior of the Lada 4×4 under the panel to the left of the steering column. Total 4 blocks:
1 — engine control system fuse box; 2 — windshield wiper relay; 3 — fuse blocks; 4 — relay block of the engine control system.
The fourth relay block is located above the gas pedal.
Main and additional fuse blocks
These two blocks are connected to each other. There are 10 fuses in the upper block, and 6 in the lower one. Markings from left to right:

- Undoubtedly, the first thing that needs to be checked is the condition of the light elements themselves. They must be free of black traces of soot, visible damage or other design flaws. If there are any, then the lamp must be replaced.

- And finally, the last (and sometimes one of the first - approx.) in line is to diagnose all the elements of the electrical circuit. This applies to both relays and fuses.
So, if during a lack of power in the low beam, the high beam is on, you can try swapping relays K4 and K5 with each other. If after such manipulations the “distant” one stops lighting, then “K4” is to blame and it needs to be replaced with a new one.

Low beam on Niva Chevrolet - lamp replacement
Burnout of low beam lamps on any car, including the Niva Chevrolet, is a common occurrence, since they are subject to the greatest wear and tear. There is no point in contacting a service center to replace them, since performing this operation yourself will only require a few minutes of free time. In this article we will take a detailed look at how to replace a low beam lamp on a Niva Chevrolet.
Low beam headlight Niva Chevrolet
So, if the low beam light on your car does not light up, then most likely the reason for this is its burnout. Accordingly, before you decide to replace it, you need to select and purchase a new lamp.
To do this, first of all, you need to figure out which low beam lamp is installed on the Niva Chevrolet. There are two types:
H7 standard halogen bulb
In our case, we will need an H7 low beam lamp - on the Niva Chevrolet, the headlight unit is divided into two compartments, respectively, separate single-filament bulbs are used for low and high beam lighting.
It is better to purchase light bulbs in sets, i.e. immediately for the right and left headlights.
Otherwise, their light spectrum may not match.
In addition, the service life of light elements is usually almost the same.
Xenon bulb H7
Of course, in addition to the design type of the lighting element, it is also necessary to pay attention to some of its characteristics. The most important parameter is the luminous flux power. It largely depends on the operating principle of the lighting element.
Below is a comparison of the power of light fluxes per watt of power of different types of lamps:
Not only the power of the luminous flux, but also its price depends on the operating principle of the lighting element. The most affordable are halogen bulbs, and the most expensive are xenon and LED.
In the photo there is an LED light bulb
It should be noted that in addition to being cheap, they also have other advantages:
Therefore, despite the lower brightness and yellowish color of the light flux, they are the most common.
You can find halogen bulbs on sale that provide a white or bluish luminous flux, close to xenon light.
Other possible faults
If the low beam headlights on a Chevrolet Niva do not light up after replacing the lamps, then the causes of the malfunction may be the following:
- Blown fuses;
- Poor contact of the connectors - in this case, the connector is easily put on the contacts and is poorly fixed, or there is noticeable oxide on the contacts;
- Break in the car wiring in the area from the headlight to the fuse box;
- Faulty low beam switch or relay - unlike previous cases, with such faults two headlights do not light up at once.
- Poor contact of the ground wire in the headlight itself - in this case, all light sources in the headlight do not light up.
In all these cases, restoring the lighting will not be difficult. The main thing is to correctly determine the cause of the malfunction. To do this, you may need a multimeter, which will allow you to determine the area of the open circuit.
The low beam on the Chevrolet Niva went out
Up. Communities › Chevrolet Niva › Blog › Low beam disappeared. makar62 last online 2 hours ago. Hi all! Tell me where to look for the low beam? Both headlights went out at once, fuses and relays are fine. 2 years. I had this happen myself. In the evening I got into the car and turned on the light, but it didn’t come on. I also couldn’t believe that two light bulbs could burn out at once, I searched all the fuses and relays. Well, the tank is always in the car, I checked the power supply. Now I always carry 2 light bulbs with me in reserve . +1. 2 years. UpLoader. Damn it was like that on the short guy. I didn’t have time to figure it out, I sold it))) And I’ll keep an eye on the solution to the problem. +1.
Please help. Chevrolet Niva, model year The low beam went out. Symptoms: 1) there are dimensions 2) there are high beams 3) when the low beam is turned on, the relay clicks 4) there is no indication that the dimensions are on on the dashboard either (but there was). How to search? 1) check the fuses (one on each side) - is there a chance that both burned out at once? 2) check the low beam relay? So the high beam and low beam relays click the same way - can you just switch them over and check? 3) check the lamps? Did they both burn out at once? - it happens? Tags: Chevrolet Niva. Lord Elektronoff "reply." check everything.

Lamp selection
So, if the low beam light on your car does not light up, then most likely the reason for this is its burnout. Accordingly, before you decide to replace it, you need to select and purchase a new lamp.
To do this, first of all, you need to figure out which low beam lamp is installed on the Niva Chevrolet. There are two types:
| Lamp type | Peculiarities |
| H4 | Double-filament (high and low beam combined) |
| H7 | Single strand |
In our case, we will need an H7 low beam lamp - on the Niva Chevrolet, the headlight unit is divided into two compartments, respectively, separate single-filament bulbs are used for low and high beam lighting.
Advice! It is better to purchase light bulbs in sets, i.e. immediately for the right and left headlights. Otherwise, their light spectrum may not match. In addition, the service life of light elements is usually almost the same.
What to look for when choosing
Of course, in addition to the design type of the lighting element, it is also necessary to pay attention to some of its characteristics. The most important parameter is the luminous flux power. It largely depends on the operating principle of the lighting element.
Below is a comparison of the power of light fluxes per watt of power of different types of lamps:
| Lamp type | Luminous flux power, 12 lm/W |
| Incandescent | 12 |
| Halogen | 16 |
| Halogen with quartz glass | 24 |
| Xenon arc | 91 |
| Light-emitting diode | 132 |
| Sodium gas discharge | Up to 200 |
Not only the power of the luminous flux, but also its price depends on the operating principle of the lighting element. The most affordable are halogen bulbs, and the most expensive are xenon and LED.
It should be noted that in addition to being cheap, they also have other advantages:
Therefore, despite the lower brightness and yellowish color of the light flux, they are the most common.

Nissan Almera Classic Club. Please login or register. Welcome to the club of Nissan Almera Classic car lovers. Home Help Search Login Register. I checked everything and can’t figure out what happened! My low beams went out on both headlights.
Previously, the lamps “burned” alternately, I changed them myself without any problems. Today I once again changed both lamps, but there was no result. The connectors do not seem to have melted.
Please tell me which fuse needs to be checked. Don't rush life, it won't get faster.. DooM Hero Member Messages: Alex65 from October 02, Gunn Hero Member card holder Messages: Thank you all for the science. Tomorrow I'll try to check everything carefully again.
The low beam relay is burned out. It is located in the relay box under the hood on the starboard side. Today I successfully fixed this problem at the dealer under warranty. Thanks again everyone. Alvas Hero Member Messages: Alex65 from October 16, I used only standard light bulbs. Now the dealer is negotiating with Nissan to replace the engine compartment harness under warranty, since there is a short one hanging somewhere. The issue has been under consideration for 3 weeks now. The dealer negotiated with Nissan for a long time and the process lasted 3 months.
And finally, the work on replacing the engine compartment wiring harness was carried out under warranty, those. For which many thanks to the dealer! Today this punishment befell me too. I checked both the fuse and relay. In short, this kind of garbage is driving and the dimensions disappear, everything else works, the fuses in the interior are all intact, the relay that is on the left leg is fine, everything under the hood is also intact, what could it be? Trying to be brief, I become incomprehensible.
Most likely the light bulb sockets have burned out. This has happened to many people. The left low beam does not light up, the light bulb, fuses and relays are ok, there is also contact with the light bulb, I couldn’t go any further, where and how should I dig next?

The low beam light does not light up: the main causes and troubleshooting
Chevrolet Niva is a joint production product of two automobile concerns - AvtoVAZ and GM. The car belongs to the crossover class, but the presence of permanent all-wheel drive makes it a good option for those who like to conquer off-road terrain. Therefore, it is very important that all components of the car work reliably, because when you find yourself far from a populated area, you need to feel confident that you will be able to get to your destination.

But over time, the service life of the parts is exhausted and problems appear with some elements. For example, components responsible for lighting may fail. In this case, it is impossible to continue moving.
The problem may be caused by faulty low beam lamps or wiring problems. First of all, you need to check the low beam lamps. Usually such a malfunction is easy to determine, since usually only one lamp out of two burns out. But what to do if the low beam is not on completely and the high beam is on. The operation of the high beam indicates that the headlight unit is working properly, a problem with the contacts has been ruled out, and it is necessary to check the rest of the wiring.
To do this, you need to ring the power wire from the relay to the fuses, the relay contacts. Even if new parts are installed, this does not mean that they are in good working order. Relays and fuses can be damaged when the engine is started if the alternator is not configured correctly.
A properly working high beam indicates that the control circuit is in order. This also means that relays K4 and K5 are connected in series and control the high beam. Those. The problem may most likely be in the K5 low beam coil.
After this, you need to check the power board. It may have a break near the fuse or between the relay and the wiring to the K5 coil.
If the circuit does not contain visible damage, it is necessary to check the contacts of relay-K5. It may make a clicking sound indicating it is working, but no signal will come out of it.
If all of the above steps did not help identify the malfunction, then you need to ring the circuit. To do this, use a multimeter or a test lamp with connected wires. It is better not to use inexpensive Chinese indicators, so as not to short the circuit.
Before performing the test, you must turn on the ignition and low beam, and then check in a certain order:
- Check the voltage at the fuses. It is quite possible that both lamps burned out as a result of a short circuit or as a result of natural wear and tear.
- After this, you need to turn off the relay and check the presence of voltage on pin 30. If it is missing, then most likely the problem is in the track from the wiring to K5
- The cover is removed from the relay, after which you need to install it back and turn on the low beam. In this case, K5 should make a click and the plate will press against the contacts. If the light does not light up, you need to manually press the plate to ensure contact. If this action helps, then the problem lies in the relay contacts. If not, the problem is in the track on the board leading to the fuses.

The track can be ringed separately. To do this, K5 is removed, the fuses are turned off, then the multimeter contacts are connected to the fuse socket and relay 87.
