Rear drivers side door will not open. Outside latch appears not to be attached internally, swings freely. Inside latch has some tension but does not feel like the same tension/tension points as the passenger side rear door. If I can't open the door I can't remove the inside body panel to trouble shoot. I have removed the panel screws. Can't get to the edges of the panel to pry open with the door closed. Tips on getting the door open are welcome.
