An HVAC system for a vehicle includes a control unit for controlling the HVAC system and an air recirculation unit controlled by the control unit that is operable in an automatic mode and a manual mode. In the automatic mode, the air control unit is operable to determine if a sunroof is applied to the vehicle, determine if the control unit can determine whether the sunroof is open or closed, determine if the sunroof is open or closed, and change an operating condition of the air recirculation unit in the automatic mode from a first operating level to a second operating level if the sunroof is determined to be open.
