Abstract: A vehicle air conditioning system is configured to cool a passenger compartment having a first zone and a second zone. An air handler has a recirculation door movable from a first position in which only fresh air from outside the vehicle enters the air handler and a second position in which only recirculation air from the first zone enters the air handler. A controller is connected to the first sensor, the recirculation door and a control panel. The controller is configured such that in response to the control panel being set to: provide cooling only to the second zone; the recirculation door being set to provide fresh air; and a first sensor's conditions being meet, the controller changes the setting of the recirculation door from fresh air to recirculated air to the air handler over-riding a manual setting of the position of the recirculation door.
