Check Console temp A_actuator
1. Ignition "OFF"
2. Disconnect Console temp actuator "A" and A/C control unit main harness connector.
3. Connect (+) terminal of battery to WARM (+) of Console temp actuator "A" and (-) terminal to COOL (-). (Component side)
4. Verify that the temperature actuator operates to the cool position
5. Verify that the temperature actuator operates to the warm position with reverse connecting. (WARM (+) and COOL (-) ). (Component side)

Specification : Refer the specifications in Fig. 1)
