The door cover is quite easy to remove. There are six screws that hold it on. One, (Torx head, T10 or 15) behind a cover on the door latch handle. One, (Phillips head) behind the power mirror control joystick. Two, (Phillips head) behind the courtesy light, towards the back of the door (pry it out with a small screwdriver from the rear). Two, (hex head, 9/32 or phillips) along the front edge of the door speakers (if you have that option). If you have crank down windows, there is a clip behind the crank, that you push (or pull) towards the handle ****. There is a tool available at most auto parts stores that is designed to remove this clip.
Once you have removed all of the fasteners, you should disconnect any wiring for any switches or lights that are on the door panel, including the power window and doorlock control (pry this panel out, from the bottom). Next, pull the panel straight out from the door, starting on the bottom edge. There are plastic fasteners along the bottom, and left and right edges of the door panel. The top is hooked over the inner door frame, which you will have to pull up, starting along the back (latch side) end. Tip: It helps if the window is fully lowered. Once the door panel is free, push it back about an inch, and remove the cover for the door lock from the lock rod, and disconnect the door speaker and trunk release wiring. The door panel can now be removed.
There are two brackets on the door, that need to be removed before you can remove the clear plastic inner cover from the door. The top bracket is held on by one phillips screw. The bottom one is held on with two nuts (10 mm head). Before you pull the plastic cover, which is glued on, make a note of which wires came out of which holes on the plastic. After you pull the plastic, you now have access to the insides of the door.
To re-assemble, reverse the dis-assembly process. If you break any of the plastic fasteners, you can get them from any good parts store.
