Turn the ignition switch OFF.
Disconnect the evaporator temperature sensor connector.
Measure resistance between terminal “+” and “-“ of evaporator temperature sensor.
Connect the evaporator temperature sensor connector.
Run the engine and turn the A/C switch ON, then measure the voltage between the terminals of harness connector.
