pull up on the surround around the window switches, unplug them. they will pop out. take the little cover off on the door itself that covers where the mirror bolts on.
two 7mm screws in the bottom of the panel, two 7mm screws behind the little access plate below the handle to pull the door closed.
slide the panel up and it will come free of the door.
sorry for the lack of capitalization, apparently my shift key is broken.
you'll also need to pull the power mirror switch out if you're working on the lf door.
