Chevy Impala 2000-2005 Fuse Box Diagram

Fuses and Circuit Breakers

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links in the wiring itself. 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.


Driver’s Side Instrument Panel Fuse Block

Some fuses are in a fuse block at the end of the instrument panel on the driver’s side of the vehicle. Pull off the cover labeled FUSES to expose the fuses.


Passenger’s Side Instrument Panel Fuse Block
