In this article, you will find information about the fuses of the Chevrolet Tahoe / Chevrolet Suburban (GMT1YC) (models 2021, 2022, 2023, and 2024), 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 Tahoe & Suburban
To check a fuse, look at the band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a fuse of the identical size and rating.
Replacing a Blown Fuse:
- Turn off the vehicle.
- Locate the fuse puller on the instrument panel end cap.
- Use the fuse puller to remove the fuse from the top or side, as shown above.
- If the fuse must be replaced immediately, spare fuses are also provided on the instrument panel end cap or borrow a replacement fuse with the same amperage from the fuse block. Choose a vehicle feature that is not needed to safely operate the vehicle. Repeat Steps 2-3.
- Insert the replacement fuse into the empty slot of the blown fuse.
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 access door is on the passenger side edge of the instrument panel. Pull off the cover to access the fuse block. A fuse puller is available on the right instrument panel end cap. There are relays on the back of the fuse block. To access, press the tabs and remove 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.
Rear Compartment Fuse Block:
The rear compartment fuse block is behind the access panel on the left side of the compartment. Pull the panel out by grabbing the finger access slot at the rear edge.
