In this article, you will find information about the fuses of the Chevrolet Colorado (models 2021 and 2022), 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 Colorado
The wiring circuits in the vehicle are protected from short circuits by fuses. 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.
Location of Fuse Boxes
Instrument Panel Fuse Block:
The instrument panel fuse block is behind the passenger side cowl side trim panel. Remove the plastic nut at the front of the cover, then pull the cover away from the trim panel to access the fuse block.
Engine Compartment Fuse Block:
The engine compartment fuse block is in the engine compartment, on the driver side of the vehicle. Lift the cover to access the fuse block. A fuse puller is available inside this fuse block.
