Power Windows and Other Power Options Circuit breakers in the floor console fuse block protect the power windows and other power accessories. When the current load is too heavy, thecircuit breaker opens and closes, protecting the circuit until the problem is fixed. 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. Look at the silver-colored L-Band inside the fuse. If the L-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 don't havea and spare fuse, you can borrow one that has the same amperage or use one of the spare fusesin the underhood fuse and relay center. Just pick some feature your of vehicle that you can get along without like the radio or cigarette lighter - and use its fuse,if it is the right amperage. Replace it as soon as you can. There are two fuse blocks in your vehicle: the floor console fuse block and the underhood fuse block. Headlamp Wiring The headlamp wiring is protected by different fuses located in the underhood fuse block. An electrical overload may cause the lamps to go off and remain that way. If this happens, replace the right fuse with one of the same kind and amperage. Windshield Wiper Fuses The windshield wiper motor is protected by an internal circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, be sure to get it fixed. 5-98
