In this article, you will find information about the fuses of GMC Terrain (models 2016 and 2017), 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
Fuses The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of damage caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse.
Caution!
- Replace a bad fuse with a new one of the identical size and rating.
- 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 located on the passenger side panel of the center console.
- To access the fuses, open the fuse panel door from the passenger side by pulling it out.
- To reinstall the door, insert the tabs on the top of the door into the console first, then push the door back into its original location.
