good question.
If you turn on the defroster and open the hood, you should notice the compressor cycling some. Also might put a gauge on it to be sure the refrigerant is ok. If the refrigerant is lo, it could still engage the clutch on the compressor but disengage quickly because of the "built in" safety that keeps it from running long enough to suck air in the sealed system if you have a leak.
redlightningsvx made a good point with moisture getting into the car from an outside source that could cause extra moisture on the windows. Even a small heater core leak that could only slowly seep out moisture?
My bet is the air conditioner not functioning properly!
Good luck...
