The heater and fan assembly regulates the air flow coming from the air intake for further processing and distribution.
In the heater heat exchanger, heat from the engine coolant is transferred to the incoming air.
The temperature damper regulates the amount of air passing through the heater's heat exchanger. In addition, the temperature damper regulates the air temperature by controlling the mixing of heated and outside air.
The mode flap regulates the flow and distribution of treated air into the air ducts of the interior heater and windows.
