In this article, you will find information about the fuses of the Chevrolet Cavalier (models 2003, 2004, and 2005), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Chevy Cavalier
The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of damage caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and don’t have a spare fuse, you can “borrow” one that has the same amperage. Just pick some feature of your vehicle that you can get along without – like the radio or cigarette lighter – and use its fuse if it is the correct amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the instrument panel fuse block and the engine compartment fuse block.
Caution!
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire.
Location of Fuse Boxes
Instrument Panel Fuse Block:
The fuse panel is located at the driver’s side of the instrument panel. To open, push the tab on the access door to the left and pull the door forward. Make sure to insert the tabs when replacing the cover.
Engine Compartment Fuse Block:
The engine compartment fuse block is located on the driver’s side of the engine compartment. Lift off the cover to check the fuses.
