GMC Vandura and Chevrolet G20, G30 (1988-1992) Fuse Diagram

Checking and Replacing Fuses

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible links. This greatly reduces the chance of damage caused by electrical problems.

Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.

Note

Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. This can cause damage to the electrical system and fire.
Never replace a broken fuse with anything other than a new fuse. Use always an intact fuse of the same color.
If a fuse blows again contact a qualified service center.
