I have a 2007 with dual zone climate control. When it is set on any temperature the air is cold until I hit 90 degrees then I get heat. Any Ideas on where to start looking?
Thanks.

The SS3's with automatic climate control have several temp sensors throughout the vehicle and ducting, seems like it could be the one measuring cabin temp-located in driver side b-pillar, another possibility is the HVAC control unit itself.. If it were me I would find a control unit out of a junkyard tb with the auto cc and swap em out.. easiest part to rule out as the culprit.

Thanks for sharing this knowledge and I agree with you.

Those are surprisingly cheap to get from a salvage yard. Go pull it yourself and save a few more $$$
