Chevrolet S-10 Blazer (1982-1994) Fuse Diagram • FuseCheck.com

Checking and Replacing Fuses

The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of damage caused by electrical problems.

To check a fuse, 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.

Fuses of the same amperage can be temporarily borrowed from another fuse location if a fuse goes out. Replace the fuse as soon as possible.

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.

Instrument Panel Fuse Box

The fuse panel is located under the dashboard.
