Fuses and Circuit Breakers The wiring circuits your vehicle are protected from short circuits by a in combination of fuses, circuit breakers, and fusible thermal links in the wiring itself. This greatly reduces the chance of fires caused by electrical problems. See "Fuses and Circuit Breakers" in the Index for more information. Headlamps The headlamp wiring is protected by a circuit breaker in the lamp switch. An electrical overloadwill 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. 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 and not snow, etc., be sure to get it fixed.

When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed or goes away.
