Operation

1. The front body control module (FBCM) turns on the blower relay based on the blower ON signal sent from the climate control unit.

2. When the blower relay turns on, the blower motor fan rotates.

3. The rotation speed of the blower fan is determined by the transistor in the power MOS FET. If the current value flowing through the transistor is high, the rotation speed increases, if the current value is low, the speed decreases.
