Blower / Recirculation System





BLOWER/RECIRCULATION SYSTEM
The blower motor, fan, and recirculation control door that switches fresh air ventilation/recirculation, are inside the blower housing.

On the bottom of the case, there is a power transistor to change the motor speed activated by the heater fan switch.

A servo motor above the fan activates the recirculation control doors.
