The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links.
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.
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 right amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the floor console fuse block and the underhood fuse and relay center.
