In this article, you will find information about the fuses of the Chevrolet Avalanche (GMT900) (models 2007, 2008, 2009, 2010, and 2011), 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 Avalanche
The wiring circuits in the vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links. 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.
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. You and others could be seriously injured or killed.
Location of Fuse Boxes
Instrument Panel Fuse Block: The instrument panel fuse block access door is located on the driver side edge of the instrument panel. Pull off the cover to access the fuse block. The center instrument panel fuse block is located underneath the instrument panel, to the left of the steering column.
Engine Compartment Fuse Block: The Engine Compartment Fuse Block is located in the engine compartment, on the driver side of the vehicle. Lift the cover for access to the fuse/relay block.
