I'm pretty sure the Volvo ACC (Automatic Climate Control) even reduces the fan speed accordingly at higher road speeds.

it can't be that. I am not talking about a slight gust, a gentle draft. This looks like blower is on. It's freezing our feet. The mid vents are pointed upwards because even though they are shut, they keep blowing, and so does the windshield vent!
This has to be some kind of gasket that is faulty or I don't know what. But it can't be by design. It's like you basically have the blower turned on one (at least) with all vents opened at the same time.
I don't kow how this system is designed. What is it that make sthe air circulate one way or the other when you turn the vents knob? Is it a flap inside the ducts?
