Repair Procedures: Inspection

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

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

  4. Connect the mode control actuator connector.
  5. Turn the ignition switch ON.
  6. Check the voltage between terminal 6 and 5.
    VOLTAGE SPECIFICATION

    Door position Voltage (V) Error detecting
    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 the 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.
