Fuses andCircuit Breakers The wiring circuits in your vehicle are protected from short circuits by a 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 overload will cause the lamps to flicker 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. Although the circuit is protected from electrical overload. overload due to heavy snow, etc., may cause wiper linkage damage. Always clear ice and heavy snow from the the windshield before using the windshield wipers. If the overload is caused by some electrical problem and not snow. etc., be sure to get 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. This protects the circuit until the current load returns to normal or the problem is fixed. Trailer Wiring Harness The seven-wire trailer wiring harness is protected by an in-line fuse in the battery feed wire. This fuse is near the junction block. See "Trailer Wiring Harness" in the Index for more information. 6-75
