Heating or cooling I don’t get much air out of the upper passenger vent. Now, looking at air flow diagrams I should always have air flow out of them. The center vent and lower vents are modulated during varying temperature conditions. It looks like a straight path from the main air plenum that houses the coils to the left and right vents. So I don’t see why the vents would be closed. Maybe the ducting hose slipped off since there seems to be no damper there to malfunction. Anyone else seen this in their W124?
