How do you take the left front door panel off on a 2000 Pontiac Bonneville to access the window regulator and wiring?

Remove the door handle then all screws you can find. tehn the ratainers on the sides and bottom of the door. You need a special tool to get to the retainers. When aoo is loose, pull out on the bottom, push in on the top of the panel and raise it up to disengage the door.
