3. Operate the temperature control dial (passenger side). Check that the discharge air temperature (passenger side) changes.
4. Press the DUAL switch, and then check that the temperature setting (LH/RH) is unified to the driver side temperature setting.
Is the inspection result normal?
YES - GO TO 10.
NO - With 7 Inch Display and perform the appropriate diagnosis.
10.CHECK AUTO MODE
1. Press the AUTO switch, and then check that "AUTO" is shown on the display.
