Repair Procedures: Inspection

WARNING: This page is about a different car, the 2014 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.

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.

TEMPERATURE CONTROL ACTUATOR SPECIFICATION

Door Position	Voltage (V)	Error Detecting
Max. cooling	0.3±0.15	Low voltage: 0.1V or less High voltage: 4.9V or less
Max. heating	4.7±0.15	Low voltage: 0.1V or less High voltage: 4.9V or less

It will feedback the current position of the actuator to controls.

If the measured voltage is not within specification, substitute with a known-good temperature control actuator and check for proper operation.
Replace the temperature control actuator if it is proved that there is a problem with it.
