An air-handling system for a vehicle includes a housing defining a first flow path through which a first flow of air is configured to selectively flow and a second flow path through which a second flow of air is configured to selectively flow. A heat exchange passageway provides fluid communication between the first flow path and the second flow path within the housing. A heat sink is disposed within the heat exchange passageway and is associated with cooling a linear power module of a blower assembly disposed within the housing. The heat sink is configured to exchange heat with air disposed within the heat exchange passageway to provide cooling of the linear power module regardless of a mode of operation of the blower assembly.
