    This vehicle has the ability to store codes in the hvac control module as long as someone is using a Factory scan tool.
    There are 3 doors / actuators: blend door ( temp), mode door ( defrost, floor, vent) and recirc door (outside air vs. Inside air)
    Sounds like a problem with the mode door. Should be verified with a scan tool ( Tech 2)
