BMW PM-FT module used on
BMW E38 7-series, E39 5-series and E53 X5
Last updated October 10, 2016
The PM module is used on cars that use the BMW GM3 module like the E38 7-series 1994-2001, E39 5-series 1995-2004 and E53 X5 1999-2006.
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 car wiring diagram you will see connector numbers X1128, X1129 & X887 on the drivers side door and connector numbers X1130, X1131 & X889 on the passengers side.
The window motor is controlled via a V23078-L1002-A303 relay which is the quiet version of the V23078-C1002-A303
The door lock is controlled via a Solid State Driver IC, ST Microsystems L9947S and the outside mirrors are controlled by a quad H-bridge IC, ST Microsystems L9705. 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.
