My Right Rear door is locked shut on my 1999 4.0se and I need advise on how to get it open so I can remove the lock mechanism for inspection, cleaning, adjustment or possible replacement. I have the door panel removed and the foam pealed back but this is way back in there. It acts like the car is locked up and the inside and outside handles are not contacting anything inside when you pull on them. It also feels like the electronics are working but not doing anything. thanks for looking
