E30 door lock problem
Does your car have remote power locks? Can you lock the driver's door from the outside with the key? There are 2 lock settings with a key only system. One position just locks all the doors, the other is the security lock which can ONLY be unlocked from the driver's door.
Sounds very like a faulty motor on the driver's door.
Could be a bad motor. But I'd also unplug the connector to the door as the pins at the bottom can rust out.
Inside the driver's door.
No, I do not have the remote locking system. The key will lock and unlock the driver door, or it can be done from inside the car. I wouldn't think it to be just the motor since the other locks don't lock from there.
