Last weekend, my climate control started to act up. It was blowing cold air out of the center vents, the drivers and passenger temperature display showed "00"
I could not change the temperature on the touch screen or the manual buttons, they were locked up. But I could change the fan speed. The a/c, defrost and recirculate buttons all would light up when touched, but did not change anything with the air flow or temperature.
Since I could not drive it due to fogging on the windshield and freezing interior temperatures, I was going to get it towed to the dealer.
Before towing it, I tried the Sync system master reset. It did not help.
Then I tried removing the 12 volt battery cable and waited for 10 minutes. When I reconnected it, then the climate control started to work normally and I could drive it again. And so far it has been ok.
Since the system started to work after disconnecting the battery, I believe that it is a software issue. But this 1 month old 2014 is supposed to have the latest updates already.
I realize that it should have been checked for codes by the dealer first before disconnecting the battery, but I was stuck and had no choice but to try and disconnect the battery as towing would be the last resort.
So the question is, why did it happen in the first place? Software issue? Hardware issue?
