Step	Check	Yes	No
1 VISUALLY CHECK FRESH/RECIRC DOOR OPERATION. Remove the glove box. Refer to REMOVAL . Operate the FRESH/RECIRC switch, and visually check the intake door operation.	Does the intake door operate normally?	Is the position between the intake door and intake door case sealed completely? System is normal.	Go to step 2 .
2 CHECK A/C CONTROL PANEL. Turn the ignition switch to ON. Using the Subaru Select Monitor, check "Fresh/Recircle Air Door Actuator Position Target" of the current data from the A/C diagnosis. Operate the FRESH/RECIRC switch.	Does "Fresh/Recircle Air Door Actuator Position Target" indicate 0 ↔ 100?	Go to step 3 .	Replace the A/C control panel. Refer to REMOVAL .
3 CHECK CONNECTOR. Check the connecting condition of connectors (i186), (i181) and (i80).	Is there poor contact?	Repair the connector.	Go to step 4 .
4 CHECK FUSE. Remove the fuse No. 7 and No. 22 from fuse & relay box. Check the fuse.	Is the fuse OK?	Go to step 5 .	Replace the fuse.
5 CHECK POWER SUPPLY FOR INTAKE DOOR ACTUATOR. Turn the ignition switch to OFF. Disconnect the intake door actuator connector (i186). Turn the ignition switch to ON. Measure the voltage between intake door actuator connector (i186) and chassis ground. Connector & terminal (i186) No. 7 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Go to step 6 .	Check for open or short circuit in the harness between intake door actuator and fuse.
6 CHECK HARNESS BETWEEN A/C CM AND INTAKE DOOR ACTUATOR. Turn the ignition switch to OFF. Disconnect the A/C CM connector (i181). Measure the resistance between intake door actuator connector (i186) and A/C CM connector (i181). Connector & terminal (i186) No. 1 - (i181) No. 3: (i186) No. 3 - (i181) No. 6:	Is the resistance less than 10 Ω?	Go to step 7 .	Repair the open circuit of harness between A/C CM and intake door actuator.
7 CHECK OPERATION OF INTAKE DOOR ACTUATOR. Connect the intake door actuator connector (i186). Ground the A/C CM connector (i181) with a suitable wire. Turn the ignition switch to ON, and check the operation of intake door actuator. Connector & terminal (i181) No. 3 - Chassis ground:	Does the actuator move to the FRESH side?	Go to step 8 .	Replace the intake door actuator. Refer to REMOVAL .
8 CHECK OPERATION OF INTAKE DOOR ACTUATOR. Turn the ignition switch to OFF. Ground the A/C CM connector (i181) with a suitable wire. Turn the ignition switch to ON, and check the operation of intake door actuator. Connector & terminal: (i181) No. 6 - Chassis ground:	Does the actuator move to the RECIRC side?	Replace the A/C CM. Refer to REMOVAL .	Replace the intake door actuator. Refer to REMOVAL .
