2019 Colorado 3.6L V6
Engine Bay Fuse Box
Two Tabs On Clip
This automotive maintenance tutorial was specifically written to assist owners of the second generation (2015, 2016, 2017, 2018, 2019, 2020, 2021 and 2022) GM Chevrolet Colorado truck in checking or changing a blown fuse or a faulty relay in either the engine bay or interior passenger compartment electrical panels.

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.


Pinch Together Tabs
Release Rear Clip
Pull Off Fuse Box Cover
To release the retaining clips, pinch or squeeze together the two tabs towards each other.

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

Fuse Location Diagram
Plastic Fuse Puller Tool
Pull Tool Off Panel
Turn over the cover to view the fuse location diagram.

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.

Passenger Side Foot Well
Fuse Access Cover
Spin Off Thumb Nut
The interior passenger compartment electrical panel is located in the front passenger seat foot well.

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.

Remove Plastic Panel
Interior Fuse Block
Place Tool Over Old Fuse
Gently pull off the access cover and set it aside.

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.


Pull Out Old Fuse
Hold Up To Light Bulb
Push In New Fuse
Pull the old fuse straight out of the socket.

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.

Line Up Access Cover
Push Cover In Place
Turn Nut Clockwise
To replace the access cover, first re-insert the tabs on the rear edge (closest to you).

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

Thumb Nut Secured
Access Cover Replaced
Replace Fuse Puller Tool
Spin on the thumb nut in the clockwise direction until it is snug.

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.

Line Up Fuse Box Cover
Push To Secure Clips
Electrical Fuses Replaced
Lower the cover over the top of the engine bay electrical panel.

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,
