86 635CSi Just acquired my first 6er. When the A/C is running in order to get adequate air flow from the driver's vents I have to close the upper center vent. Is this normal? Also, the fresh air flap control still appears to work when the A/C is on. Sliding the vent control to the right while driving at highway speed increases air flow from driver and center vents. Thought it was supposed to be inoperative when the A/C is on. Any help/advice would be appreciated. Thanks!
