A/C window fogging and defoster

[Deserion]

Not sure if that can be controlled, though I know what you mean. My old Mercedes does the same thing.

If I'm not wrong, that is the way it's suppose to be.
If you want to get cold air thru the defroster vents, you have to press the upper right button (the one with the arrow up icon)
I will check it tomorrow in my car, and will let you know, if it dose the same.
