Using the multi-tester, measure resistance between terminal "1" and "2" of the evaporator temperature sensor.
Turn the ignition switch OFF.
Disconnect evaporator temperature sensor.
Using the multi-tester, measure resistance between terminal "1" and "2" of the 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 the harness connector.
