There are four screws holding the door panel to the door itself. Two are at the bottom of the door panel, one is behind the latch handle, and the fourth is sort of "Inside" the grab bar on the door. The arrows in the accompanying photo point to the four locations.

Once the four screws are out lift straight up on the door and it will disengage from several slots in the door. DO NOT try to move it very far yet! Lift it up and lean away from the door enough so you can see behind it and get your hand in there. Unplug the connector for the windows and door locks. The passenger side connector has a clip on top that you need to push down to release the connector. The driver side has a red lock that needs to be slide out to unlock the connector so that it can be disconnected. Also, the driver side has a connector for the power mirror controls.

Disconnect the linkage from the door handle as well. The door handle linkage rod is secured by a plastic clip as shown by the left-hand circle in the photo to the right. The rod is bent so that it will slide down into the middle of the clip, and then the clip rotates and snaps onto the linkage bar itself. Just unsnap it from the rod and it will pivot out of the way so that you can lift the rod out of the clip. These clips are "Captive" so they won't go flying when you take the linkage rod out. When this is done the door panel can be lifted off completely and set aside.
