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.
