Ok, so my xb works great, only the driver side (front left) door mechanism doesnt work unless I manually use my key or my hand when unlocking. I know that the entire mechanism still works because when i press the lock button all of the doors lock. its just that unlocking of the driver door that the mechanism can't handle. I'm not sure if its just that the locking motor isnt strong enough to push the lock back up, or there is too much resistence not letting it come beck up when its trying to lock. All I know is that it is frustrating when I unlock my car from the outside remotely and all the doors unlock except for the driver door (most imprtant). Ahhh its annoying. Anyone have any similar obstacle or suggestions???

Replace the door lock actuator.
