a plurality of outlets;
a sliding control door downstream of the evaporator and configured to allow air to flow across one or both of a heated path across the heater and a bypass path bypassing the heater; and
a sliding stratification door downstream of the control door and positionable to, in an intermediate position, direct the air flowing through the bypass path to be mixed with air that flowed across the heated path before flowing out of the plurality of outlets;
wherein the air is mixed within a bypass cavity; in a full cold position, the stratification door is in a retracted position within an upper exit cavity to unobstruct the bypass path; and the plurality of outlets includes a defrost outlet and an upper vent outlet, and the upper exit cavity is provided fluidly between the bypass cavity and the defrost outlet and upper vent outlet.
