WARNING: This page is about a different car, the 2012 Hyundai Veloster. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition "OFF"
- Disconnect the connector of temperature control actuator.
- Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 4 and grounding terminal 3
Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
- Check the voltage between terminals 6 and 7.VOLTAGE SPECIFICATION
Door position Voltage (6-7) Error detecting Max. cooling 0.45 ± 0.15V Low voltage: 0.1V or less Max. heating 4.55 ± 0.15V High voltage: 4.9V or more It will feedback current position of actuator to 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.
