If this happens, haveyour headlamp wiring checked right away.Windshield Wiper FusesThe windshield wiper motor is protected by a circuitbreaker and a fuse. If the motor overheats due to heavysnow, etc., the wiper will stop until the motor cools. Ifthe overload is caused by some electrical problem andnot snow, etc., be sure to get it fixed.Power Windows and Other Power OptionsCircuit breakers in the fuse panel protect the powerwindows and other power accessories. When thecurrent load is too heavy, the circuit breaker opensand closes, protecting the circuit until the problem isfixed or goes away.Fuses and Circuit BreakersThe wiring circuits in your vehicle are protectedfrom short circuits by a combination of fuses andcircuit breakers.Look at the silver-colored band inside the fuse. If theband is broken or melted, replace the fuse. Be sure youreplace a bad fuse with a new one of the identical sizeand rating.If you ever have a problem on the road and don’t havea spare fuse, you can “borrow” one that has the sameamperage. Just pick some feature of your vehicle thatyou can get along without -- like the radio or cigarettelighter -- and use its fuse if it is the correct amperage.Replace it as soon as you can.6-57
