Window fogging during cold and humid days..Problem?
It seems that every time it rains and is cold outside (which happens two weeks out of the year here in Texas) my front windshield fogs up. Then i turn my defrost on and it (very powerfully i may add) defrosts my windshield in 5 seconds. Then the cycle starts up again.
I found that this tends to be frequent when i have the vents closed and am circulating the air within the cab. When i open the vent and have my heater on, it doesn't happen...
Any one else have this issue? How do y'all deal with it?

Happens to me too, its pretty annoying. It was really bad last month, but for whatever reason it hasn't really been a problem this month. But i blamed this on the fact that i left my sunroof open on a day it was drizzling 2 months ago. I hope that was the reason, cause turning the defroster on and off every min is really annoying lol.

If you have the vent closed on recirculate the system will not dehumidify the air in the cabin and this will happen on wet or humid days and nights. It can be very dangerous if it happens at the wrong time.

Extremely common, and not just on the IS. You shouldn't turn off the A/C compressor in recirculate mode. Just set the temperature to a comfortable set point, and the AC will operate with re-heat to dehumidify the air.
