In this article, you will find information about the fuses of GMC Terrain (models 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 GMC Terrain/Terrain Denali
The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the electrical load current is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems.
Caution!
- Replace a bad fuse with a new one of the identical size and rating.
- Use of an oversized fuse or circuit breaker can result in a vehicle fire.
- Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
Location of Fuse Boxes
Engine Compartment Fuse Block:
To remove the fuse block cover, squeeze the clips on the cover and lift it straight up.
Instrument Panel Fuse Block:
The instrument panel fuse block is under the instrument panel on the driver side.
- To access the fuses, press and release the latch near the top center square.
- Apply pressure to the two retaining tabs on the sides of the cover, until the two retaining tabs clear the sides of the instrument panel.
- Allow the panel to move downward and out of the way.
- To reinstall the cover, reverse the steps.
Rear Compartment Fuse Block:
The rear compartment fuse block is behind a trim panel on the side of the rear compartment. Remove the trim plate to access the fuse block.
Electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off.
If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart.
