Relays and fuses for Chevrolet Cruze sedan, hatchback, station wagon (1.6 and 1.8): block diagrams
Fuses are designed to break because they prevent the entire system from being overloaded. They are the noble victims of the electrical world.
Locate your vehicle's fuse panel. You may need to take apart the owner's manual, but they can usually be found under the steering wheel. It also makes sense to look under the hood. You need to remove the Chevrolet Cruze fuse panel cover. Inside you'll see a series of colors and numbers that represent different amperages, while a diagram (usually on the back cover) will show you what each fuse does in your car. Find the fuse that is blowing. If the item is knocked out, the inside will usually be black or the metal thread may be broken. If it's dark, you may need a flashlight to make this faster. We take out the broken fuse if its exact pinout is known. You can use various tools to remove a blown fuse
Fuses can break easily, and a broken fuse is much more difficult to remove than a completely intact fuse. Insert a new, replacement fuse (or replacement fuses) of the correct amperage - refer to the fuse panel and owner's manual. Using a fuse of the wrong amperage can cause serious problems in the circuit. Keep several extra fuses of varying strengths
In a jam, you can always take the fuse out of the lesser used function with the same amperage and use it for something more pressing, but that's just a temporary solution. For example, if the fuse for your power windows blows and there is no rain in the forecast, take the working fuse allocated to the rear window and use it for the power windows. Just double check that the amperage for each is the same. Start the ignition to see if your work has paid off. If the same fuse fails soon after replacement or fails at all, it may be time for a trip to a mechanic for a diagnosis.
Where are the fuses located on a Chevrolet Cruze?
Even a novice car enthusiast can replace Chevrolet Cruze fuses on his own after studying the material we offer. The process itself is simple and, knowing what is located where, you can do it in just five to ten minutes.
The fuses in the car are located in fairly accessible places. In order to get to them, you do not need to remove bulky components or dismantle complex systems. The first is located in the engine compartment on the right side at the rear, near the battery.
Second, in the cabin on the left, behind the glove compartment
It is very important to learn how to change them, because their failure is a common occurrence. It would be stupid to immediately go to a service station if something in the electrical equipment has failed or the cigarette lighter has simply stopped working
You can first try to fix the problem yourself.

- Where is the fuse box located?
- Under the hood - number 12
- To gain access to the fuses in the engine compartment, you need to release the three latches of the block cover, then remove it.
- On the inside of the cover there is a diagram of the location of fuses, relays and fuse links.

Before replacing a fuse in a Chevrolet Cruze, find out the cause of the blown; if you replace the fuse and it blows again, you need to contact an auto electrician.
Do not change fuses to a different rating or jumper, this may lead to a fire or failure of the electrical equipment protected by this fuse.
The purpose and amperage of the fuses are shown in the table below.

In some cases, you can restore your device using simple manipulations. Below is a table with repair recommendations.
Breakdown option | Repair |
Faulty contact points | Adjust the metal clips using a flat-head screwdriver. |
Appearance of rust or oxide stains | Use a file or sandpaper to rub the rusty areas down to the metal base. |
Faulty protective element | Change the cigarette lighter fuse in the mounting block marked F6 with a rating of 20 amperes. |
Broken cables | Check the integrity of the cables using a tester, solder or replace broken cords. |

Relay structure and its purpose in a car
The principle of operation of any standard relay in a car is the closure or switching of two contacts on a power electrical circuit using an electromagnetic field. Closing the contacts directly through the switch will require the use of thick wires and will lead to a voltage drop in the entire on-board network. A switch with an electromagnetic coil inside allows a low current to close the desired contact and apply voltage to a section of the circuit. Through it, headlights, heating and cooling fans, power windows, a starter and other components are powered in a Chevy Niva car.
A typical fuel pump relay 75.3777-10 has 4 contacts, a coil with an armature, and a spring for opening the contact. When voltage is applied to the control contacts, the rod is drawn into the winding and another pair of contacts is closed. It turns off automatically as soon as the low-current connectors are de-energized.
Advantages of using relays in Niva Chevrolet cars:
- spontaneous leakage current in the on-board system is eliminated;
- reliable control of all electric motors;
- quick and guaranteed start of electrical mechanisms;
- Network overload protection.
The fuel pump relay has appeared on cars of the Chevrolet Niva family since 2003, when an injection engine was installed. The engines of the VAZ 21213 family are equipped with a carburetor and do not have a relay in the fuel supply system.
Chevrolet Cruze fuses: diagram, block location
Modern cars are relatively reliable and safe. They are created taking into account the maximum period of trouble-free operation. However, there are times when sensitive electronics fail, breaking down at the most inopportune moment.
Chevrolet Cruze fuses do not fall into the category of problem parts. But due to various reasons, breakdowns still occur. This can happen either due to a short circuit or due to the inexperience or illiteracy of the owner.
Next, let's look at where the main fuses are located on the Chevrolet Cruze, as well as which one is responsible for what.
Removal and replacement process
There are cases when, after replacing a certain element, the breakdown is not resolved. Even after complete maintenance of the suspected location of dysfunction, the malfunction remains
In this case, the manufacturer recommends paying attention to the seat itself.
There are often times when the main part is fully operational, there are no short circuits in the wiring, but the car still behaves inappropriately. In this case, further diagnostics takes on drastic methods. We are talking about completely replacing the fuse box with a known good one, or, in other words, a new one. The reason is the burnout of the tracks.
To effectively dismantle the blocks, certain manipulations must be performed. To do this, you do not need to take the car to a mechanic at a service station. The whole procedure can be done at home using a primitive set of tools.
Replacing the engine compartment
To replace the engine compartment fuse box, you need to perform the following sequence of actions.
- Disconnect the positive terminal of the battery.
- Using a 10mm wrench, unscrew the three panel fixing bolts.
- Use a flathead screwdriver or similar tool to pry off the mounting terminals.
- Remove the block from its seat.
- Unscrew the bundle of wires from the end.
Replacing the interior unit
For the interior part, the sequence of actions is as follows:
- Turn off power to the battery.
- Remove the lower part of the dashboard.
- Disconnect the wire block from the element.
- Then you need to pull the unit up and towards you.
After replacement, assembly must be carried out in the reverse order.
