Repair procedures
| Inspection |
| 1. |
Turn the ignition switch OFF. |
| 2. |
Disconnect the temperature control actuator connector. |
| 3. |
Verify that the temperature control actuator operates to the warm (LHD) or cool (RHD) position when connecting 12V to the terminal 3 and grounding terminal 4. Verify that the temperature control actuator operates to the cool (LHD) or warm (RHD) position when connecting in the reverse.
|
| 4. |
Connect the temperature control actuator connector. |
| 5. |
Turn the ignition switch ON. |
| 6. |
Check the voltage between terminal 6 and 5 (LHD) or 7 (RHD). Specification
It will feedback current position of actuator to controls. |
| 7. |
If the measured voltage is not specification, substitute with a known-good temperature control actuator and check for proper operation. |
| 8. |
If the problem is corrected, replace the temperature control actuator. |
| Replacement |
| 1. |
Disconnect the negative (-) battery terminal. |
| 2. |
Remove the driver side shower duct (A) after loosening the screw.
|
| 3. |
Disconnect the connector (A) and then remove the temperature control actuator (B) after loosening the mounting screws.
