B0363 CHEVROLET Meaning

The Heating, Ventilation, and Air Conditioning (HVAC) Control Module commands the air temperature actuators to move by controlling the voltage supplied on the control circuit. A signal voltage of 0 volts or a signal voltage of 5 volts rotates the air temperature actuator. A voltage of 2.5 volts stops the door. The HVAC control module determines the current position of the actuator by monitoring the voltage on the signal circuit. The feedback potentiometer is a function of the motor position. The HVAC control module controls the air temperature actuator door positions in order to maintain the selected air temperature.
