Easy check... with door opened, use a screw driver or something to operate the latch to fully latched ( 2 clicks I think ). Does the lock work? If so the door striker isn't properly operating the latch mechanism. These Chrysler bodies are so soft at the latch post that we can grab the post with pliers and change its angle. Striker may be leaned downward and/or inward from square with the latch where door hinges are failing. My striker needed some correction after the hinges were renewed.
