E46 central locking issue

The car is a 200 323i. The locking system stopped working on the driver's door only. Well, it works partially. I can LOCK all doors with the remote
key but when I try to UNLOCK all doors unlock (including trunk) except the driver's door. I have to unlock manually with key. Same thing with internal locking switch... will LOCK all doors and UNLOCK all except the driver's door.
Also, when trying to LOCK all doors using the key manually (not the remote) the doors will not lock.
I suspect a faulty driver's door actuator/motor. Any ideas of a different possible cause?
