It would be your front door lock actuator. It is a solenoid that when it goes bad it just freezes in whatever position it is in.
Best to buy used from someone parting out an e34, but make sure it is a pre-1993 model year, they changed the design of it then. The dealership will charge $100+ for that piece.

I've got one left, but I need to replace mine so I'm going to have to keep it for myself.

Good luck though!
