Humidity in windshield defroster
 
I have an 04 Colorado and this morning I turned the defroster on and it foged up all of my windows. It was plenty hot, just really humid. I am familiar with the smell of coolant, and I didn't notice any odor coming from it what so ever. Anyone have any idea what could be happening? I'm kind of thinking it may have something to do with the AC compressor, but that is just a guess.

Evaporator freezeup. Take one of the lower vent lines off and drain the water. Evap freezes up and they dont have a fix for it. Its happening with a brand new Colorado i just bought.
