The AC comes on because it de-humidifies the air blowing on the glass. This
is a good thing. But if you don't want the AC running, try using the
setting for "windshield and feet". It does not automatically turn on the
AC. Also, as others have mentioned, turn off re-circulate. You have to use
fresh air to get rid of the fog.
