I just got a 2007 Subaru Forester sport 2.5X and after getting the AC fixed the inside of the windshield fogged up. The AC was on, set to blow fresh air at me. When I noticed the windshield getting foggy I checked it was set up the way I would set it for defrosting in the winter and turned it to blow on the windshield. The fogging got IMMEDIATELY worse to the point I had to pull over turn the air off and open the windows.
