- Turn the ignition switch OFF.
- Disconnect the temperature control actuator connector.
- Verify that the temperature control actuator operates to the warm position when connecting 12V to terminal 3 and grounding terminal 4.
Verify that the temperature control actuator operates to the cool position when connected in reverse.
- Connect the temperature control actuator connector.
- Turn the ignition switch ON.
- Check the voltage between terminal 4 and 5.VOLTAGE SPECIFICATION
Door Position Voltage (V) 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 the current position of the actuator to the controls.
- If the measured voltage is not specification, substitute with a known-good temperature control actuator and check for proper operation.
- If the problem is corrected, replace the temperature control actuator.
