The wiring circuits in your vehicle are protected from short circuits by a combination of fuses. This greatly reduces the chance of fires 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 you replace a bad fuse with a new one of the identical size and rating.

Upper Fuse Block

Some fuses are in a fuse block in the engine compartment on the passenger's side of the vehicle. See Engine Compartment Overview for more information on location.
