yellowblue MaxifuseR/Relay Center 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 damage 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. 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. To check the fuses in this underhood fuse center, turn the two knobs one-quarter turn counterclockwise and loosen the metal wing nut on the passenger's side of the cover. Then remove the cover. The inside of the cover has a chart that explains the features and controls governed by each fuse and relay. There are two fuse blocks in your vehicle: the driver's side and passenger's side fuse blocks. 6-62
