The wiring circuits in the vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links in the 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 to replace a bad fuse with a new one of the identical size and rating. Spare fuses and a fuse puller are located in the underhood fuse block. See Underhood Fuse Block later in this section.
Some fuses are in a fuse block located on the end of the instrument panel on the passenger side.
To get to the fuse block lift up on the side panel. A fuse usage chart is on the inside of this panel.
