Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. 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 you 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. You can remove fuses with the fuse puller. Remember to replace any of the spare fuses you use, so you will have some if you ever need them again. If you ever have a problem on the road and don't have a spare fuse, you can borrow one that has the same amperage. Just pick some 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. Instrument Panel Fuse Block The fuse block is located on the lower portion of the instrument panel on the driver's side. There are two fuse blocks in your vehicle: one is inside the vehicle and one is in the engine compartment. 5-93
