Removing the panel is fairly straight forward.
1. you need a small socket, 1/4" I believe for the two bolts in the arm rest, a putty knife (or a thin piece of stock) to slide in and release the trim around the inside door handle, and an upholstery removal tool for the clips that hold the panel to the door (available at any parts store cheap) You can use a broad screw driver instead of the removal tool but usually end up marking the door and breaking some clips.
2. Remove the trim around the inside door handle by inserting the putty knife and sliding it along until you feel the retainer. A slight twisting motion will cause the retainer to release, repeat on the other retainers. There are three, if memory serves me well.
3. Remove the two bolts from the arm rest.
4. Start at the bottom of the door, using the upholstery removal tool, release the clips holding the panel to the door.
5. Remember that you have speaker wires and door control wires to disattach prior to removing the panel. Depressing the dentent release on each should allow you to disconnect them. I've had more grief with these than anything each when removing the door panel. A small blade screwdiver comes in handy for depressing the detents.
6 Installation is the reverse of removal.
Take your time and look it over well, it is very straight forward and uncomplicated once you have it off.
Best of Luck
