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 4. Verify that the temperature control actuator operates to the cool position when connecting in the reverse. [Drive]
1. - 2. - 3. Hot position 4. Cool position | 5. Sensor ground 6. Feedback signal 7. 5V (Vcc)
4. | Check the voltage between terminals 5 and 6(Drive). Specification
Door position | Voltage(5-6) | Error detecting
Max. cooling | 0.4 ± 0.15V | Low voltage :0.1V or less
Max. heating | 4.6 ± 0.15V | High voltage :4.9V or more

5. | Check the voltage between terminals 6 and 7(Passenger). Specification
Door position | Voltage(5-6) | Error detecting

Max. heating | 4.6 ± 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(A).
4. | Remove the crash pad lower cover (A).
5. | Disconnect the diagnosis connector (A).
6. | Remove the reinforcing panel (A).
7. | Remove the shower duct (A).
8. | Disconnect the temperature control actuator connector (A).
9. | Loosen the mounting screw and then remove the temperature control actuator (B). [Drive]
10. | Remove the right extension cover (A).
11. | Disconnect the damper (A) from the glove box (B).
12. | Remove the glove box lift (A).
13. | Disconnect the pine (A), then remove the glove box (B).
14. | Remove the crash pad passenger panel(A).
15. | Remove the glove box housing (A).
16. | Remove the shower duct (A).
17. | Disconnect the temperature control actuator connector (A)
18. | Loosen the mounting screw and then remove the temperature control actuator (B). [Passenger]
19. | Installation is the reverse order of removal.
