Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow or ice, the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it fixed. 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. Power Windows and Other Power Options Circuit breakers in the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed. Instrument Panel Fuse Block The instrument panel fuse block is located under the instrument panel on the passenger side of the vehicle. Pull down on the cover to access the fuse block. 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. 490
