Its a long time since I removed the door trim, but here goes.
There are four screws at the bottom of the door trim underneath the trim part of the door, remove these.
There is a screw retaining the inner door handle, remove that carefully. This will separate the handle from the
door trim, see pic.
There maybe screws in the armrest, check, and remove if there are.
Pull the lower part of the trim away from the door a couple of inches, make sure the door handle is free and doesn't follow
with the trim.
Then push upward until the trim lifts off the top of the door.
The window control switches can be disconnected after or before but I think it is easier to disconnect them after as they are not that
easy to remove first without damaging the wood surround (I think I pushed them out from behind).
Secure the door handle without kinking the wire.
Good luck /Paho
