Electrical System Add-On Electrical Equipment Notice: Don't add anything electrical to your vehicle unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage wouldn't be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-76. Windshield Wiper Fuses The windshield wiper motor is protected by an internal fuse in the underhood fuse block. 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. The rear washer pump is controlled by a relay located in the engine compartment, behind the windshield washer fluid reservoir. The rear wiper motor is protected by a fuse located in the instrument panel fuse block. Power Windows and Other Power Options Circuit breakers in the instrument panel 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. Headlamp Wiring The headlamp wiring is protected by four internal fuses in the underhood fuse block. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. 5-97
