That is why you should run your DEFROSTER for the first 10 minutes you are in your car in the winter.
The Defroster uses the AC to dry the moisture from the air before it is heated and directed at your windshield.
If warm moist air was directed at your windshield, in the winter, it would
condensate immediately on the windshield, and block your view.
This is what I was always lead to believe, except that my service manual says that the A/C cycling switch prevents the compressor from operating below 50 deg F ambient temp to prevent evaporator freezing.
