Check Intake actuator
1. Ignition "OFF"
2. Disconnect Intake actuator and A/C control unit main harness connector.
3. Connect (+) terminal of battery to FRE (+) of intake actuator and (-) terminal to REC (-). (Component side)
4. Verify that the actuator operates to the REC position
5. Verify that the temperature actuator operates to the FRE position with reverse connecting. (REC (-) and FRE (+)) (Component side)

Specification : Refer the specifications in Fig.1)

FIG.1) ** Function of the actuator motor according to terminal connection type. (observe safety regulations)
6. Is "Door position" display near the specified value?





Check potentiometer
1. Ignition "OFF"
2. Disconnect Intake actuator and A/C control unit main harness connector.
3. Ignition "ON" (ENGINE "OFF").
4. Measure voltage between Signal (F/B) terminal of Intake actuator harness connector and chassis ground. (Component side)

Specification : Refer the specifications in Fig.2)
