Fuse Box Diagrams Chevrolet Impala (2000-2005)

In this article, you will find information about the fuses of the Chevrolet Impala (models 2000, 2001, 2002, 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.

Chevrolet Impala (2000-2005)

Checking and Replacing Fuses in Chevy Impala

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of fires 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.

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.
