2007 Cadillac Escalade

First remove what is called the upper extension, it is the triangle piece in the front on the inside of the mirror, pull at top until retainer disengages, then lift. Remove the plate behind the inside door handle revealing a screw, and remove the plate in the pull handle pocket revealing two screws, remove all screws. Pry up on the window switch, I find it best to do the pull handle end first, there is a retainer at the front and rear of switch, disconnect the electrical. Remove the lock rod knob by disengaging the square plastic piece. Using a pry tool, work your way around the outsides of the panel disengaging the push in retainers. That should get you most, if not all the way. Below is the service manual procedure if it helps any further, I think there are some discrepancies in it, as far as fastener number.
