Headlight Wiring The headlight wiringis protected by a circuit breaker in the light switch. An electrical overload will cause the lights to go on and off,or in some cases to remain off. If this happens, have your headlight system checked right away. 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 willstop until the motor cools. If the overload is caused by some electrical problem, have it fixed. 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.
