Owners of other General Motors vehicles from Chevrolet, GMC, Cadillac, Buick and Holden such as the Trax, Equinox, Traverse, Blazer, Tahoe, Suburban, Sonic, Cruze, Trailblazer, Spark, Malibu, Impala, Volt, Bolt, Corvette, Camaro, Silverado, Express, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, Canyon, Sierra, Terrain, Acadia, Yukon, XT4, XT5, XT6, Escalade, CT5, CTS, XTS, CT6, ATS, Astra and Commodore may also find these DIY instructions to be helpful.

The Colorado is equipped with standard mini blade electrical fuses that can be purchased at any auto parts store, at Walmart on online at Amazon.

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

The rectangular shaped black plastic fuse box is situated just to the right of the engine cover and to the right of the 12V automotive battery.

There are three retaining clips on the fuse box cover. They are situated at the front edge, rear edge and left side.

Once all three clips have been released, carefully pull the cover straight off the top of the engine bay fuse box.

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

A white plastic fuse puller tool is situated near the front left (passenger) side corner of the engine bay fuse panel.

Pull the tool straight off the mounting bracket.

Spin off the black plastic thumb nut at the front edge of the access cover (located closest to the front of the truck).

Set the thumb nut aside in a safe place.

To remove an old fuse, squeeze the end of the white plastic tool to open the jaws.

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

To check the condition of the old fuse, hold it up to a light bulb.

If the thin metal bar or band in the translucent plastic center of the old fuse appears to be burnt or broken, the old fuse is most likely "blown" and should be replaced.

Push a new mini blade electrical fuse of the same amperage rating (e.g. 5A, 10A, 15A, 20 Amps) straight into the socket.

If the thin metal strip in the middle of the old fuse appears to be intact, the old fuse is probably still good.

Since new fuses are so inexpensive, it should still be replaced as part of your electrical issue troubleshooting problem.

If you would like to add a hard-wired power source for an automotive accessory such as a dashcam (dash camera), radar detector, gauges, GPS navigation unit, cell phone charger or a lighted LED Uber or Lyft sign, install an "Add-A-Circuit" fuse tap.

To find a circuit that has switched (only live when the ignition switch is on) or constant 12V power, use a digital multimeter tool.

Then push the hole on the front edge (closest to the front of the truck) over the threaded stud for the thumb nut.

Push the fuse puller tool back into place on the engine bay fuse panel.

If you suspect that a faulty relay is the source of your electrical problem, the easiest way to troubleshoot it is to simply replace it with a new relay of the same amperage rating.

Alternatively, you could test the old relay with a digital multimeter tool.

Push on the cover to secure the three retaining clips.

You should feel or hear the retaining clips "click" securely into place.

Check the electrical component that you were having problems with such as the windshield wipers, stereo, horn, power driver's seat, etc.

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