2010 - 2014 Chevrolet Tahoe Suburban Fuse Box Diagram

2014 Chevrolet Tahoe

Fuses and Circuit Breakers

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.

Engine Compartment Fuse Block

L - Engine Compartment Fuse Block Location

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.

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

To remove fuses, hold the end of the fuse between your thumb and index finger and pull straight out.
