2014 Chevrolet Silverado Fuse Box Diagram

2014 Chevrolet Silverado

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.
Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as you can.
