The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links in the wiring itself.
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.
Five spare fuses are provided in the engine compartment fuse block. If you ever have a problem on the road and do not have a spare fuse, you can borrow one that has the same amperage. Just pick a feature of your vehicle that you can get along without -- like the radio or cigarette lighter -- and use its fuse, if it is the correct amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the instrument panel fuse block and the engine compartment fuse block.
There is a fuse puller located on the engine compartment fuse block. It can be used to easily remove fuses from the fuse block.
