The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing Your Airbag-Equipped Vehicle on page 2 ‑ 66 and Adding Equipment to Your Airbag-Equipped Vehicle on page 2 ‑ 67 . Fuses and Circuit Breakers The wiring circuits in the 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. Just pick some feature of the 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. Headlamp Wiring The headlamp wiring system has four individual fuses. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have the headlamp wiring checked right away. Windshield Wiper Fuses The windshield wiper motor is protected by an internal circuit breaker. If the wiper motor overheats due to heavy snow, the wipers will stop until the motor cools and will then restart. A fuse powers the wiper motor. If the fuse blows, there is an electrical problem. Be sure to have it fixed. Underhood Fuse Block The underhood fuse block is located on the passenger side of the engine compartment. Remove the fuse cover and secondary service cover to access the fuse block. Notice: Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component. Power Windows and Other Power Options Circuit breakers in the fuse block 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 or goes away. 6-103
