For 1990-2009 cars only

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links.

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.

If you ever have a problem on the road and don't have a spare fuse, you can borrow one that has the same amperage or use one of the spare fuses in the underhood fuse and relay center. Just pick some feature of your vehicle that you can get along without - like the radio or cigarette lighter - and use its fuse, if it is the right amperage. Replace it as soon as you can.

There are two fuse blocks in your vehicle: the floor console fuse block and the underhood fuse and relay center.

Floor Console Fuse Block


Object Number: 822411  Size: B3

The floor console fuse block is located to the left of the glove box near the floor.

The fuses marked spare are available if a replacement fuse is needed.

Pull the door open to access the fuse block.
