Have a 93 green Bonny and love it except one problem: I'm new here and having trouble with the remotes control opening the rt. rear door. It will lock it ok , but not unlock. Took the door panel off and the actuator appears to work. There is a white plastic that appears to be broken near the end where it attaches to the locking rod. Is this really broken or is that how it works? Is it possible the actuator can work in the closing position and not the open position? Any help or advise would be appreciated.
