I just received my Model X last week and the rear vents aren't blowing enough air. I’ve been researching online after realizing the B pillar vents aren’t putting out any wind, that the 5 seater only has 1 ac unit. Meaning no wind from the pillars, and the middle vents are shared with the vents up front and it’s barely blowing any air out. So my kids are sweating in the back seat, while we are freezing up in the front trying to cool down the whole car. I’m getting the car tinted tomorrow, so hopefully that’ll help, but I feel pretty bad after spending $100k, that my kids wont be as cool as us up in the front. Am I missing something here?
