Climate Control System: Notes

Refer to AIR CONDITIONING (Explorer) or AIR CONDITIONING (Mountaineer) Wiring Diagrams for schematic and connector information.

• moves the temperature blend door on command from the DATC module.
• contains a reversible electric motor and a potentiometer. The potentiometer wiper is connected to the actuator output shaft and moves with the output shaft to indicate the position of the temperature blend door.
• apply a 5 volt signal to one end of the potentiometers and ground to the other. The voltage available at the wiper indicates the position of each potentiometer. The expressed value of the actuator wiper voltage is sent to the DATC module and is matched with an expected wiper voltage value. The DATC module then drives the actuator motor in whichever direction is necessary to make the actuator wiper voltage agree with the expected DATC module wiper voltage value.
