This automotive maintenance tutorial was specifically written to assist owners of the first generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GMC Terrain in checking or changing a faulty or "blown" fuse or relay in either the engine bay or the interior passenger compartment electrical panels.

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Acadia, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

This 2016 Terrain is equipped with standard mini blade fuses which can be purchased at any auto parts store, Walmart or online at Amazon.

A white plastic fuse puller tool should be included on the engine bay electrical panel. If the tool is missing, you may use a pair of needle nose pliers with rubber insulated handles.

Engine Bay Fuse Block
The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

The engine bay fuse box is located just behind the 12V automotive battery and to the right of the brake fluid reservoir.

There are two tabs on both the left and right sides of the engine bay fuse box cover.

Pinch the two tabs on each side towards each other to release the retaining clips.

Lift off the fuse box cover to access the electrical panel.

Hold Up To Light Source
Place the jaws of the tool over the old fuse and gently pull it straight out of the socket.

Hold up the old fuse to a light bulb to check it.

If the thin metal band or strip in the translucent plastic center of the old fuse appears to be broken or burnt, the fuse is most likely burnt or "blown" and should be replaced with a new fuse of the same amperage rating (e.g. 5, 10, 15, 20A).

If the thin metal bar in the middle of the old fuse appears to be intact, the fuse is probably still good. But since new fuses are so inexpensive, you should still replace the old fuse as part of your electrical issue troubleshooting process.

Replace Fuse Puller Tool
Push a new mini blade fuse of the same amperage rating straight in to the socket.

If you suspect that a relay is faulty, the easiest way to check is to replace it with a new or another known to be working relay on the panel.

Otherwise you can check the relay by using a safe 12V power source (not the car battery) and a multi-meter.

Replace the fuse puller tool in to its holder at the front right corner of the engine bay fuse block.

Pop In Access Panel
Push the fuse box cover back in to place until the two retaining clips "click".

Line up the interior fuse block cover and gently snap it back in to place.

Test the electrical component that you were having problems with such as the radio, 12V socket, window wipers, power seat, power windows, radio, headlights, interior lights, etc.

If you are still having the same problem, you might have a shorted wire somewhere or the component itself needs to be replaced.
