There is a cover behind the interior door handle, and behind the door pull (the handle you grab to shut the door), remove those covers and you will reveal 10mm bolts, remove those. Take off the lock/unlock tab (thing that goes up/down when you lock or unlock). Next remove the window switch by lifting the panel up with a flathead screwdriver, the tabs holding it will pop loose.
Then, starting from the very bottom, take a flathead but be very careful, and pry the door panel enough to get your fingers in there and pull. The panel has many clips that will start popping out of place. Once you get them all, you can use needle-nose pliers to release the cable from the door handle, and your panel is off.
