Air Distribution Flap Motor: Notes

The air distribution flap motor has the task of setting the air distribution via central kinematics over a cam disc.

The air-distribution control wheel can be used to select the following programs for air distribution:

• Air distribution to the windows
• Air distribution to the upper body area
• Air distribution to the windows, to the upper body area and into the footwell
• Air distribution into the footwell

If the air-distribution control wheel in the control panel of the heater/air conditioning system is used to set the desired air distribution, the control unit for the heater/air conditioning system activates the air-distribution-flap motor.

The cam disk is connected to the air-distribution-flap motor and adjusts the air-distribution flaps via the central kinematics.

The drive consists basically of following parts:

• Air-distribution-flap motor (actuator drive)
• Electronic module (with integrated switching circuit)
• Transmission
• Housing
