yellowblue Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. 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. 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. 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. There are two fuse blocks in your vehicle: the underhood fuse block and the rear compartment fuse block. Underhood Fuse Block The underhood fuse block is located next to the engine air cleaner/filter on the driver's side of the engine. Lift the cover to gain access. 6-63
