  2. Test the humidity/in-car temperature sensor while holding it in front of the dashboard center vent
    • Measure the resistance with the system set to Max Cool
    • Measure the resistance with the system set to Max Hot
  3. Compare the resistance reading between terminals No 4 and No 3 of the humidity/in-car temperature sensor with the specifications shown in the graph, the resistance should be within the specifications
