My 2003 Z4 3.0i decided to quit letting me select which air vents to use. It started out intermittent and now it only sends air to the floor. But, I can't find how BMW actuates the vent system to select upper dash (defrost), side and center vents on the dash, or the floor vent.
Any help or links to a pdf would really be appreciated. Right now, I can't use the front defrost or select the dash vents.
Any ideas? I know it's got to have some sort of actuator to operate a diverter, but where is that?
