2001 Intrigue - RH door won't open‏
 

I just purchase a used 2001 Intrigue and it has some minor problem. One of the problems is the RH side door won't open. The power lock button locks and unlocks all doors except the RH door, lock make no sound. The key manually doesn't move the lock and the inside lock doesn't move.

Any suggestion what to do to free the locking system on this door or how to get inside the door without destroying the door panel.?
