Its fogging behavior has changed, though.  I've had it for two years and
it's never been like this.  45 degrees F today and normal humidity, and it
fogged up in about 10 minutes with 3 in the car.  Increasing fan speed
doesn't help, only cracking the windows.

Also, does it seem reasonable with the outside temperature at 45, interior
temperature set to 66, and pressing AUTO that the A/C would come on?
