Inspection

1. | Ignition "OFF"

2. | Disconnect the connector of temperature control actuator.

3. | Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 3 and grounding terminal 7. Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
[Drive]

1. - 2. - 3. Cool position 4. 5V (Vcc) | 5. Feedback signal 6. Sensor ground 7. Hot position

4. | Check the voltage between terminals 5 and 6(Drive). Specification

Door position | Voltage(5-6) | Error detecting
Max. cooling | 0.3 ± 0.15V | Low voltage :0.1V or less
Max. heating | 4.7 ± 0.15V | High voltage :4.9V or more

[Passenger]

1. - 2. - 3. Cool position 4. 5V (Vcc) | 5. Feedback signal 6. Sensor ground 7. Hot position

5. | Check the voltage between terminals 5 and 6(Passenger). Specification

Door position | Voltage(5-6) | Error detecting
Max. cooling | 0.3 ± 0.15V | Low voltage :0.1V or less
Max. heating | 4.7 ± 0.15V | High voltage :4.9V or more

It will feedback current position of actuator to controls.

6. | If the measured voltage is not specification, substitute with a known-good temperature control actuator and check for proper operation.

7. | If the problem is corrected, replace the temperature control actuator.

Replacement

1. | Disconnect the negative (-) battery terminal.

2. | Remove the crash pad left side cover (A).

3. | Remove the extension cover. (Refer to BD group - "Crash Pad")

4. | Remove the crash pad lower cover (A).

5. | Disconnect the connector (A) & diagnosis connector (B) and then remove the crash pad lower cover.

6. | Remove the reinforcing panel (A).

7. | Remove the shower duct (A).

8. | Remove the BCM (A).

9. | Disconnect the temperature control actuator connector (A).

10. | Loosen the mounting screw and then remove the temperature control actuator (B). [Drive]

11. | Remove the right extension cover (A).

12. | Remove the crash pad lower cover (A).

13. | Disconnect the connector (A) and then remove the crash pad lower cover.

14. | Remove the crash pad garnish (A).

15. | Remove the center facia panel (A).

16. | Disconnect the damper (B) from the glove box (A) and then remove the glove box lift (C).

17. | Disconnect the pine (A), then remove the glove box (B).

18. | Remove the glove box housing (A).

19. | Remove the shower duct (A).

20. | Disconnect the temperature control actuator connector (A).

21. | Loosen the mounting screw and then remove the temperature control actuator (B). [passenger]

22. | Installation is the reverse order of removal.
