Take out one screw lower right of that door panel.
Take out TWO screws under the inside door pull handle black section.
Pull the whole inside door handle section off the big door panel.
Take out one screw that's behind that door handle section.
Lift the ENTIRE door panel straight up, then pull out.

The piece at the top is thermally welded to the main door panel.
