High Blower Speed

When the High blower speed is selected, the HVAC control assembly applies voltage to the blower motor resistor assembly through the high blower motor control circuit. The voltage energizes the blower motor relay, causing the blower motor to be connected to the battery positive voltage circuit. The blower motor is included in the series circuit by the blower motor supply voltage and ground circuits. The blower motor resistor assembly provides a pathway to ground for the blower motor.
