    Stuck on defroster

    Today I went use the A/C and the air only blows out of defroster. It seems stuck on defroster. No matter what I select, feet/chest, etc it will not get out of defrost even though it selected for other setting. Anyone have this problem?

    2013 ATS 2.0T standard, CUE, power sunroof.

    Take it to the dealer and ask them to update the HVAV modulator. It's not a CUE update, it different.

    Took it the dealer and they updated the CUE system, only. It solved it.

    I know its alittle late but, I got to the dealer this afternoon and I wasn't even there for 30min. Atlantaguy00 was right they updated the HVAV and thats it.

    The tech told me that 2 other people came in prior and had the same problem. One person had it stuck on the main vents and the other on defrost.

    It's possible when I had my CUE updated, they also did the HVAC update as well.
