A climate control system for a vehicle having a plurality of modes includes an evaporator having a downstream face. The system also includes at least one blower that blows air across the evaporator. The air downstream of the blower has a pressure distribution defined generally along the downstream face. The pressure distribution along the downstream face is variable depending on which of the plurality of modes the climate control system is currently set.
