3. Using Subaru Select Monitor, check the following data of the data monitor. Ref. to AIR CONDITIONER(DIAGNOSTICS)>Data Monitor .
  - Blower Fan Level
  - Fresh/Recircle Air Door Actuator Position Target
Does [Blower Fan Level] indicate 0, and [Fresh/Recircle Air Door Actuator Position Target] indicate 100%?
- Yes : Go to 2.
- No : Replace the A/C control panel. Ref. to HVAC SYSTEM (HEATER, VENTILATOR AND A/C)>Control Panel>REMOVAL .
CHECK BLOWER MOTOR.
