I noticed driving today to work that the air flow changed from whattappeared to be the floor to the windscreen area. The setting was for the center vents and i noticed a change as this happened. i know on older american cars that some of the actuators were vacumm controlled but in looking at the manual it appears that on the 530i e34 that they are controlled via cable.
Could someone shed some light on this. It doesn't occur when parked only while i am driving, and it is difficult to look over and drive down the raod at the same time.
I also have noticed a decrease in the amount of airflow when this happens also.
Many thanks
