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.
