Yesterday my beloved 330 presented me with a new issue - upon pressing the door lock button in the center console, or by locking the doors via remote, the front passenger door will not lock or unlock. The little toggle just won't go up or down.
The toggle moves if you manually unlock or lock (either by pushing toggle down to lock or pulling door lever to unlock).

Any advice on how to go about fixing this would be greatly appreciated!
