In this article, you will find information about the fuses of the Chevrolet TrailBlazer (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 TrailBlazer
Fuses and circuit breakers protect power devices in the vehicle. If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. 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 in the engine compartment fuse block.
- Use the fuse puller to remove the fuse from the top or side.
- If the fuse must be replaced immediately, 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 is on the underside of the driver side instrument panel. To remove the storage compartment, use the hole at the top to pull the compartment outward from the instrument panel.
Engine Compartment Fuse Block:
To remove the fuse block cover, squeeze the clip and lift it up.
Rear Compartment Fuse Block:
The rear compartment fuse block is behind a cover on the driver side of the rear compartment. To access the fuses, remove the cover.
