The underhood fuse block in the engine compartment is located on the driver's side of the vehicle near the battery. Lift the cover for access to the fuse/relay block.
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 for more information on its location.
