PINPOINT TEST 6: INCORRECT/ERRATIC DIRECTION OF AIRFLOW FROM OUTLETS - HYBRID
Normal Operation
To rotate the mode door actuator clockwise, dual automatic temperature control (DATC) module supplies voltage to the FLOOR/DEFROST/PANEL mode door actuator motor through circuit (Y/GY), and supplies ground through circuit (W/L). To rotate the mode door actuator counterclockwise, the DATC module reverses the voltage and ground circuits.The mode door actuator feedback resistor is supplied a ground from the DATC module through circuit (GY/L) and a 5-volt reference voltage on circuit (BR/W). The DATC module reads the voltage on the mode door actuator feedback circuit (Y/V) to determine the mode door actuator position by the position of the actuator feedback resistor wiper arm.
