Description |
The mode control actuator is located at the heater unit.
It adjusts the position of the mode door by operating the mode control actuator based on the signal of the A/C control unit. Pressing the mode select switch makes the mode control actuator shift in order of Vent → Bi-Level → Floor → Mix.

Inspection |
1. |
Turn the ignition switch OFF. |
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 4. Verify that the mode control actuator operates to the vent mode when connected in reverse.
|
4. |
Connect the mode control actuator connector. |
5. |
Turn the ignition switch ON. |
6. |
Check the voltage between terminal 6 and 5. |
7. |
If the measured voltage is not within specification, check the operation by replacing the existing mode control actuator with a new genuine part. After that, determine whether replacement of the temperature control actuator is required or not. |
Replacement |
1. |
Disconnect the negative (-) battery terminal. |
2. |
Remove the temperature control actuator. (Refer to Heater - "Temperature Control Actuator") |
3. |
Disconnect the connector (A) and then remove the mode control actuator (B) after loosening the mounting screws.
|
4. |
To install, reverse the removal procedure. |
