Electrical System Add-On Electrical Equipment Headlamp Wiring The headlamp circuit is protected by individual fuses in the underhood electrical center. An electrical overload will cause the fuse to blow. If this happens, have your headlamp system checked right away. 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 air bag system. Before attempting to add anything electrical to your vehicle, see "Servicing Your Air Bag-Equipped Vehicle" in the Index. Windshield Wipers The windshield wiper motor is protected by a 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, have it fixed. Power Windows and Other Power Options A circuit breaker in the driver's side fuse panel protects 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. 6-60
