Chevrolet Cruze Fuse and Relay Diagram

The main part of the fuse elements on the Chevrolet Cruze is located in the engine compartment.

Depending on the modifications, there are only three blocks that are responsible for different parts of the electronic circuit of the vehicle.

It is prohibited to change the fuse rating to a higher one or insert it into the jumper socket - this can cause a wiring fire, leading to irreversible consequences.

Main block with relays and fuses

The main fuse block of the Chevrolet Cruze is located in the space between the battery and the left wing. You can find it by the square plastic cover, closed with three latches.

Opening the protective panel reveals a full set of fuses

The reverse side of the unit shows a diagram of the location of the fuses and relays. There are also special tweezers to facilitate the removal and replacement procedure.

Removal and replacement process

There are cases when after replacing a certain element the breakdown is not solved. Even after a complete service of the supposed place of dysfunction, the malfunction remains. In this case, the manufacturer recommends paying attention to the seat itself.

There are often moments when the main part is completely serviceable, there are no short circuits in the wiring, but the car still behaves inadequately. In this case, further diagnostics acquire radical methods. We are talking about a complete replacement of the fuse box with a known good one, or, in other words, a new one. The reason is the burnout of the tracks.

Replacing the underhood fuse box

To replace the underhood fuse box, you need to perform the following sequence of actions.

• Disconnect the positive battery terminal.
• Use a 10 mm wrench to unscrew the three panel fixing bolts.
• Use a flat-head screwdriver or similar tool to pry up the mounting terminals.
• Remove the unit from its seat.
• Unscrew the bundle of wires from the end.

Replacing the cabin fuse box

For the cabin part, the sequence of actions is as follows:

• Disconnect the power supply to the battery.
• Remove the lower part of the instrument panel.
• Disconnect the wiring block from the element.
• Then you need to pull the unit up and towards you.
