In this article, you will find information about the fuses of the Chevrolet Blazer (models 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 Blazer
The vehicle has fuses and circuit breakers to protect against an electrical system overload. 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.
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 inside the center console on the passenger side of the vehicle. Remove the fuse access door by inserting a coin or tool into the slot of the access door.
After accessing the fuses, ensure the fuse block cover is reinstalled, if equipped. To reinstall the fuse panel door, push the door back into its original location.
Engine Compartment Fuse Block:
The underhood fuse block is in the engine compartment, on the driver side of the vehicle. To remove the fuse block cover, press the clips on the cover and lift it straight up.
Caution!
- Do not pull the engine compartment fuse block lever, since it is intended only for service purposes. If pulled, vehicle malfunction may occur.
- Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
Rear Compartment Fuse Block:
The rear compartment fuse block is behind a trim cover on the driver side of the rear storage compartment. Remove the trim cover to access the fuse block or visit your dealer. The fuse block label is located on the central bin.
