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.

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.

There is also a fuse location diagram in the owner's manual.

The white plastic fuse puller tool is located at the front right corner of the engine bay fuse block.

The interior passenger compartment electrical panel is located behind a plastic cover on the passenger side kick panel below the center stack.

There is also a fuse location diagram in your owner's manual.

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.

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.

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.
