Owners of other General Motors vehicles such as the Chevrolet Impala, Monte Carlo, Malibu, Spark, Sonic, Cruze, Volt, SS, Camaro, Caprice, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado, Buick Verano, Regal, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra, Terrain, Acadia, Yukon, Savana, Cadillac CT6, ATS-V, ATS, ELR, CTS, XTS, XT5, SRX, Escalade and Holden Commodore may also find these DIY instructions to be helpful.

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

The engine bay fuse box is located on the right side just behind the driver side headlight assembly and next to the 12V automotive battery.

The fuse box cover is held in place by three retaining clips. There is one on the left side, another on the right side and a third one on the rear (near the windshield).

To release the retaining clips, gently pinch (squeeze) together the two prongs towards each other as illustrated in the picture above.

Lift the fuse box cover straight off to access the engine bay electrical block.

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

The white plastic fuse puller tool is located near the right (driver side) rear corner of the engine bay fuse block.

The storage compartment drawer is in front of where the driver's left knee would normally reside while driving.

You'll also find another diagram in the owner's manual.

Squeeze the end of the fuse puller tool to open the jaws.

Place the jaws over the old fuse you'd like to check or change.

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

If the thin metal band or "strip" in the translucent plastic center appears to be broken or burnt, the old fuse is most likely faulty or "blown" and should be replaced with a new one.

If the thin metal bar in the middle of the old fuse appears to be intact, it is probably still good. Since new fuses are so inexpensive, it should still be replaced as part of your electrical problem troubleshooting process.

Push a new mini blade fuse of the same amperage rating (e.g. 5, 10, 15, 20, 25) straight in to the socket.

Line up the fuse box cover and push it down to secure the three retaining clips.

Then squeeze together the two sides of the drawer and re-insert the plastic side stops behind the dashboard.

Close the storage compartment to complete the job.

Test the electrical component that you were having issues with such as the radio, wiper blades, interior lights, headlights, 12V socket, horn, power door locks, power windows, etc.

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