  1. Switch "OFF" the ignition.
  2. Disconnect the mode control actuator connector.
  3. Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 7.

    Verify that the mode control actuator operates to the vent mode when connected in reverse.

  4. Connect the mode control actuator connector.
  5. Switch "ON" the ignition.
  6. Check the voltage between terminals 4 and 5.
    DOOR POSITION AND VOLTAGE SPECIFICATIONS

    Door position Voltage (V) Error detection
    Vent 0.3 ± 0.15 Low voltage: 0.1V or less
    Defrost 4.7 ± 0.15 High voltage: 4.9V or more

    It will feedback the current position of the actuator to controls.

  7. If the measured voltage is not within specification, substitute with a known-good mode control actuator and check for proper operation.
  8. Replace the mode control actuator if it is proved that there is a problem with it.
