For some reason, my Highlander seems to trap moisture inside the car. When I turn it off, after a minute or so, I hear some things moving around the vents (dampers or gates or something, maybe?), and then when I return and it’s anywhere close to freezing or colder, then I have heavy fog and possibly ice on the inside window. When the air kicks on, the fog gets even worse before finally clearing up.

I can scrape ice on the outside of my window, but this is thr only car I’ve had that freezes I side, and I hate it. Does anybody know why it does this? What was the point of designing the vents to close shortly after turning off thr car? Why are things this way?!
