The blower switch passes on a control voltage (0 - 6 V) to the blower regulator (A32n1) via the AAC push-button control module (N22) and the AC bus. Depending on the control voltage which is present, this then regulates the blower motor operating voltage (0 - 12 V). This facilitates blower speed control of 0-100 %.

The Auto button can also be used to select

The blower regulator then controls the blower motor operating voltage, depending on the actual measured in-car temperature and the selected target temperature

(0-12 V). This facilitates blower speed control of 0-100 %.
