IHKR2 Blower Control:

The IHKR2 blower motor is hard-wired to ground. The power circuit is used to control blower speed.

The blower switch supplies voltage to the blower resistor assembly, which contains three low-resistance resistors. Blower switch position determines how many resistors are bypassed and, therefore. how much voltage is applied to the blower motor.
