Auxiliary Medium Blower Speed

When the Medium blower speed is selected, the auxiliary HVAC control module applies a ground for the auxiliary blower motor. Voltage is routed from the auxiliary blower motor, through the high blower motor control circuit, through a resistor in the auxiliary blower motor resistor assembly to achieve the desired auxiliary blower speed. The circuit is grounded by the medium 1 blower motor control circuit, auxiliary HVAC control assembly and ground circuit.
