For 1990-2009 cars only

The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of damage caused by electrical problems.

Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.

There are two fuse blocks in the vehicle: one in the engine compartment and one in the trunk.

There is a fuse puller located on the rear compartment fuse block. See Rear Compartment Fuse Block. It can be used to easily remove fuses from the fuse block.
