Hello all. Recently took delivery of my Model Y and I am learning a lot about it. I know that the front passenger vent is supposed to turn off when there is no passenger sitting in the seat but that does not seem to always happen. Sometimes I will look at the AC controls and see that the passenger side has stopped blowing but most of the time on my commute to work, I see that the passenger side vent is still open. Does any one know how this is supposed to work? Does it open both vents to bring the cabin to the desired temperature first and then turn off the unneeded vent? Please let me know.
