    2003 Z4 AC only vents air to floor

    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?
