2021 Chevrolet Colorado Fuse Box Diagram

2021 Chevrolet Colorado

Fuses and Relays

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.
If a fuse goes out, replace the fuse as soon as you can. 

Engine Compartment Fuse Block

Caution
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the
covers on any electrical component.
