The PM module is used on cars that use the BMW GM3 module like the E38 7-series 1994-2001 and E39 5-series 1995-2003.
On these cars there is one PM module in each of the Front Doors. The module is connected to the GM3 through the P-Bus. It controls the door lock, window motor, mirror motors and mirror heater. It senses the seat memory switch, door latch, window switch and mirror adjust switch and controls the appropriate motor directly and/or notifies the GM3 module via the P-Bus. If you are looking at the cars wiring diagram you will see connector numbers X1128, X1129 & X887 on this module.
The window motor is controlled via a V23078-C1002-A303
relay (I sell this relay by the way) and the door lock is controlled via a Solid
State Driver IC, ST Microsystems L9947S. The GM III were made under a variety
of part numbers including the following.

If you are having problems with the power windows on 1 door, but, everything else works then it might be a bad window relay. This relays is p/n V23078-C1002-A303 relays.
