Kia Optima: Inspection
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.

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