You just need to remove the door interior trim.
Lift the switch panel and disconnect the plug.
The arm rest pulls up to remove and reveals a couple of screws.
There is another screw underneath the small trim panel in front of the door release handle.
After that it's just clips that are released by pulling the trim away from the door.
When the clips are all released the trim panel lifts up over a small lip.
Some of the plastic clips will break when pulling the trim panel free. Hopefully not so many that you can't arrange the remaining ones to adequately secure it.
