Power Windows and Other Power Options Circuit breakersin the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breakeropens and closes. This protects the circuit until the current load returns to normal or the problem is fixed. Instrument Panel Fuse Block The fuseblock access door is on the driver's side edge of the instrument panel. Pull off the cover to access the fuse block. You can remove fuses with a fuse extractor. The fuse extractor is mounted to the fuse block access door. Fuses and Circui- - - eakers The wiring circuits in your vehicle areprotected from short circuitsby a combination of fuses, circuitbreakers 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. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. I f you ever have a problem on the road and don't have a spare fuse, you can "borrow" one that has the same amperage. Just pick some featureof your vehicle that you can get alongwithout -- like the radio or cigarette lighter -- and use its fuse, if it is the correct amperage. Replace it as soon as you can. To remove fuses if you don't have a fuse extractor, hold the end of the fuse between your thumb and index finger and pull straight out. You may have spare fuses attached the inside of to the fuse block access door. These can be used to replace a bad fuse. However, make sure that it is the correct amperage. 6-63
