Underhood Electrical Center Once you remove the cover, you will see some fuses to the top right of the fuse/relay block. These are spare fuses and can be used accordingly. You can remove fuses with a fuse extractor. The fuse extractor is located in the underhood electrical center. 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. See "Engine Compartment Overview" in the Index for more information on its location. The underhood electrical center is located on the driver's side of the engine compartment near the battery. Lift the cover for access to the fuse/relay block. 6-75
