Temperature Control Actuator

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 12 V to the terminal 3 and grounding terminal 4.

Component Location:

4. Verify that the temperature control actuator operates to the cool position when the connections are reversed.
5. Check the voltage between terminals 5 and 6.
It will feedback current position of actuator to controls.
6. If the measured voltage is not within 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.
