Below is the engine compartment fuse diagram for the Jeep Grand Cherokee second generation 1999, 2000, 2001, 2002, 2003, and 2004 model year. Your vehicle is equipped with an electrical power distribution center located in the engine compartment near the battery. This power center houses plug-in “Cartridge” fuses which replace in-line fusible links. The power center also contains “Mini” fuses and plug-in full and mini ISO relays. A label inside the latching cover of the center identifies each component for ease of replacement, if necessary.
