The wiring circuits in the vehicle are protected from short circuits by a combination of fuses, circuit breakers, and in the fuse block wiring itself. 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 a bad fuse is replaced with a new one of the identical size and rating.
Some fuses are located in a fuse block on the passenger's side of the instrument panel. Pull off the cover labeled FUSES to expose the fuse block.
