I did this a VERY long time ago.
Make sure you unscrew all of the screws, even ones hidden behind little "covers". I can't remember how many off the top of my head. Some are at the very bottom, and one is in the "change holder". Pull out the power accessories, and disconnect the harness. The door panel is held in by little plastic "poppers" that hold it to the actual door. take your time and firmly pull the door panel away until you hear little pops. If you still have any resistance, make sure that there are no screws. In another car my friend tried to pull the panel off with a screw still intact, and broke the panel.
Pull the door panel up, and then it should come off.
Sorry. This has to be one of the worst how-tos I've ever done. During break I'll run to my car to take a look
