'89 E34 A/C vent stepper motor locations? (archive)

Does anyone happen to know where the stepper motor that controls driver's side temperature is located?
Just had a problem today - full heat to the driver's side regardless of the temp selector setting. The passenger side *does* respond the full heat/full cool (master) settings on the driver's side selector, BTW.
There are 2 motors located above the driver's footwell, but I determined that one was the recirc inside air valve. The other I'm not sure of. After pulling the radio, I also saw one just right of the OBC unit but couldn't tell what it operated. Does the new Bentley manual give much info?

Any help greatly appreciated!

Motor Well,
