Pinch Together Two Tabs

This automotive maintenance tutorial was specifically written to assist owners of the tenth generation (2014, 2015, 2016, 2017 and 2018) GM Chevy Impala in checking or changing a blown fuse or a faulty relay in either the engine bay or the interior passenger compartment electrical panels.

Owners of other General Motors vehicles such as the Malibu, Cruze, Camaro, Sonic, Spark, Volt, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, SS Sedan, Bolt, Colorado, Silverado, Buick Verano, Regal, LaCrosse, Cascada, Encore, Envision, Enclave, Canyon, Sierra 1500, Terrain, Acadia, Yukon, Savana, ATS, CTS, XTS, CT6, XT5, SRX and Escalade may also find these DIY instructions to be helpful.

This 2014 Impala is equipped with standard mini blade fuses.

Some General Motors models may have the relatively newer style of low profile mini blade fuses. Please check your vehicle before purchasing new fuses.

A white plastic fuse puller tool should be included on the engine bay electrical panel and also another one on the back side of the driver side dashboard storage compartment.

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

The primary fuse box is located at the far right side of the engine bay next to the 12V automotive battery and behind the driver side headlight housing.

There are three retaining clips holding the fuse box cover in place. One is located at the front edge, another at the rear edge and the third on the right (driver) side.

Pinch or squeeze together the two tabs on the retaining clips to release them.

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

Turn over the cover to view the fuse and relay location diagram.

There is a white plastic fuse puller tool near the right rear corner of the engine bay electrical block.

Push In Side Walls
To access the interior passenger compartment electrical panel, move to lower part of the dashboard near where the driver's left knee would reside while driving.

Open the storage compartment drawer and empty out the contents.

Firmly push in the two side walls of the storage drawer until the side stops can be removed.

There is another white plastic fuse puller tool attached to the back side of the storage drawer.

Pinch the end of the tool to open the jaws and place them over the old fuse you'd like to check or change.

Pull Out Old Fuse

Hold Up To Light Bulb
2014-2018-Chevrolet-Impala-Electrical-Fuse-Replacement-Guide-018
Push In New Fuse
Pull the old fuse straight out of the socket.

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

If the thin metal strip 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.

If the metal wire inside the fuse appears to be intact, the old fuse is most likely still good. Since new fuses are so inexpensive, it 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. 5A, 10A, 15A, 20A) straight in to the socket.

(Some GM models are equipped with the relatively newer style shorter "low profile" mini blade fuses.)

To check a relay, you'll need to use a multimeter. The easiest way to troubleshoot a faulty relay is to just replace it with a new one.

Re-Insert Side Stops

Storage Drawer Replaced
Raise the storage compartment drawer and push in the side walls until the two side stops can be re-inserted.

Replace the contents of the storage compartment and close it to complete the job.

Test the electrical component you were having issues with such as the wipers, radio, power seat, power windows, tail lights, headlights, horn, interior lights, etc.

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