Blower Motor: Description and Operation

In the fresh air mode the blower (A32m1) sucks fresh air in through the fresh air flap; in the recirculated air mode air is sucked through the recirculated air flap from the vehicle passenger compartment into the heater or air conditioning housing. In the residual engine heat utilization mode the blower (A32m1) circulates the air in the passenger compartment.

The blower (A32m1) is designed as a two-stage radial fan.
