Abstract

An automotive HVAC unit includes a housing defining a first outlet adapted to connect to HVAC ductwork to provide conditioned air to a first temperature zone, a second outlet adapted to connect to HVAC ductwork to provide conditioned air to a second temperature zone, a third outlet adapted to connect to HVAC ductwork to provide conditioned air to a third temperature zone, and a fourth rear outlet adapted to connect to HVAC ductwork to provide conditioned air to a fourth temperature zone within the vehicle. The HVAC unit further includes an evaporator adapted to cool air passing therethrough, a heater core adapted to heat air passing therethrough, a blower adapted to force air through the evaporator and the heater core, and a modular insert mounted within the housing and being adapted to control the flow of conditioned air to the first, second, third and fourth outlets.
