Question E39 climate control blows a/c cold and hot

My 2002 525i blows cold a/c air on the driver's side and winds from hell on the passenger side. Both driver and passenger control temps are set to 72, the a/c is on, circulate is on, and the climate control is set to auto.

Like many other malfunctions, this only happened once, so taking the car to dealer for diagnostic testing will set me back a couple bills... and the thing is, I've had this very same problem with my prior beemer, and I kinda remember the cause of it was some dual control valve or something like that, I can't remember the exact name of the part. Does anybody know?

Thanks!
