How exactly do i go about taking off the panel to my door so i can get to my window to get it back on track. So far ive taken off the pieces that cover the door handle and the buttons to the window, and disconnected it. So now im sitting here with the door panel on and the two holes where the two pieces were. So now what do i unscrew or pull to get the doorpanel off without breaking it. A detailed explanation is needed.......thanks
