From: Jane Galt on 27 Jul 2010 23:08 When the windshield fogs up a little and we direct the vents up there to clear it, it turns the AC compressor on and freezes us. Did they seriously design the car this way, or is something wrong? Because this is NOT gonna be fun when it's 0 degrees outside and it's all we can do to heat the car, and because the vents are set on the windshield, to keep it clear, the AC is running too. -- - Jane Galt

The dry air clears the glass much faster. You can still set the temp to whatever is comfortable. The air does not have to be cold. It can be set to hot, and with the compressor on, the air will be plenty warm but dry. If the air is too cold, crank the temp setting up.

You'll never notice it. In this case, the AC is acting like a dehumidifer, removing moisture from the air and clearing the windshield faster. Works great on those days when the humidity is high, it's raining and the windows are all fogged up. The temp control blends the air coming into the cabin, so on cold days even with the ac on it's still warm. I just don't like turning on the AC every time I was to use the defroster. My Grand Voyager had a little arm in the control box that hit the AC button from inside the box when you turned on the defroster. First thing I "removed" when I found out how it worked... <SNAP!> ;) (I can activate the AC all by myself, thank you!) I wouldn't try that with your car...it's probably electronic

If the temps are below freezing, the AC light will still be illluminated but the compressor won't energize. -- Ray O (correct punctuation to reply)
