I took delivery of my new ATS when the HVAC was on ti would just go to full fan and the highest temp. Then everything would freeze on the system. The next day returned to dealer Southeast Cadillac (Charlotte) they found the same issue. Four days later new center console installed and seemed to work fine. Now what ever temp I set either sync or manuel Pass side same as driver side heater goes hot on one side then cold on other??? Keeps going back and forth. Anyone with this problem? Will bring it in this coming Tuesday. Will let you know of the fix.
