Vehicle Care 10-39 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 do not 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. Engine Compartment Fuse Block The engine compartment fuse block is located on the driver side of the engine compartment. See Engine Compartment Overview on page 10‑6 for more information on location.
