Fuses and relays are contained in two separate under hood PDC boxes as well as one in cabin block on the Jeep Commander XK. The images below are from a 2006 4.7L vehicle. The two boxes are shown the area bounded by the red box, located under hood on the driver’s side between the battery and braking system.
Underdash Fuse Block Location, notice the downward openning door in driver’s kick space just behind the OBDC connection.

Alternately, the under dash fuse set can be accessed by dropping or removing the larger driver’s side knee panel. The rectangle in red shows access into the fuse block area.
