The rear driver side door won't open from the inside or outside and window won't go up/down. Window crank just clicks. Told by the seller that it opened for them? I'm having a difficult time getting the door panel off from the inside since not being able to access the sill plate screws to remove it. It holds down interior trim. I've got the seat out. Try and pry while covering the trim? Also have had a suggestion of trying a slim jim by the latch from the outside and have someone push from the inside? Obviously don't want to damage anything. Any help would be great!
