Driver side door does not lock, using the alarm remote when pressed the alarm arms itself and the passanger door locks, The driver side door does not lock and it does not lock using the keys, I removed the panel and checked around.. the linkages seem fine and nothing looks broken or messed with..
Do you think it could be the door lock control box? or something busted with the lock itself (the part that latches to the car body) Any help or thoughts would be appreciated..
