Climate Control Question Please

Hi everyone!

bought my 07 this past spring so now that it is getting cold I have a question about using the heater

Is the air conditioning actually on when in Auto mode and the heat is coming out?

I ask because if I push the climate button the display shows the AC light is on, if I turn the AC off then I am not in Auto mode any more

or maybe the AC shows as on all year around in Auto mode but it just faking me out and does not come on unless the temps call for it?

The AC will act as a dehumidifier when the heat is on. It keeps the windows clear of condensation in the winter months.

I've had this ingoing issue since I got my car. If I have the heat up too high then the windows start to fog up. I then have to hot the defrost button which clears up the windows but also starts to push out cold outside air. I have to rinse and repeat during my whole commute. It gets annoying. I never had this issue with my 400 and I'm pretty sure it has to do with me having front and rear AC controls or not. I just can't figure it out.

Yes, leave the AC on at all times. AC doesn't mean only cold, it also means dehumidified. It's regulating humidity and heat/cold even in the winter months.

Oh, BTW, the multi-quote button is really awesome!!
