This automotive maintenance tutorial was specifically written to assist owners of the third generation (2007, 2008, 2009, 2010, 2011, 2012, 2013 & 2014) Chevrolet Tahoe in checking or changing a blown electrical fuse or relay in either the engine bay or interior passenger compartment fuse panels.

Owners of related General Motors full size SUV or truck vehicles with similar electrical fuse boxes such as the Suburban, Avalanche, GMC Yukon, Yukon XL, Yukon Denali, Sierra, Cadillac Escalade and Hummer H2 may also find these DIY instructions to be helpful.

Assortment boxes of replacement mini blade fuses in a variety of amperage ratings (5, 10, 15, 20 & 25) can be purchased at Advance Auto Parts, Pep Boys, Napa, Wal-Mart or online at Amazon.

A plastic fuse puller tool should be included on the underside of the interior passenger compartment fuse panel. 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 at the right rear area of the engine bay next to the brake fluid reservoir and close to the driver's seat.

Pull out and upwards on the left side of the box to release the top cover.

There is a fuse location diagram located on the underside of the cover and also another one in your owner's manual.

The interior fuse panel in the passenger compartment is located on the left side of the dashboard near the driver's door.

Old Fuse Removed
Grasp the handle at the bottom of the panel and gently pull it off the side of the dashboard.

There is a fuse location diagram on the back side of the cover.

A plastic fuse puller tool should be included on the underside of the passenger compartment electrical panel cover. It was missing on this 2014 Tahoe, so I had to use a pair of needle nose pliers with rubber insulated handles.

Pull the old fuse that you'd like to check or change straight out of its socket.

Push On Fuse Box Cover
Hold the fuse up to a strong light source and inspect the metal strip inside the translucent plastic center.

If the thin metal strip inside the fuse appears to be broken or burnt, then it is "blown" and should be replaced with a new one.

If the metal bar inside the center of the fuse appears to be intact, the fuse may still be good. Since new fuses are so inexpensive, the fuse should still be replaced as part of your electrical issue 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.

Lower the fuse box cover down over the panel and gently push it in to place.

Electrical Fuses Replaced
Line up the friction fasteners on the rear of the interior fuse panel cover and gently push it back in to place.

Check the electrical component that was previously not working such as the wipers, lights, radio, windows, A/C system, etc.

If it still isn't working or if the new fuse is immediately blown again, you may have a shorted wire somewhere or the faulty component needs to be replaced.
