Fixed 3 compressor discharge temperature sensor
From Service Manual 322092, p.24:
1.Check if discharge temperature sensor and holder are correctly attached; verify resistance value.
2.Disconnect the sensor and measure resistance at the sensor body. Expected: 10 kΩ to 12 kΩ at 77°F (25°C).
3.Check the sensor harness for opens and shorts. Back-probe the sensor pins at the control board connector; a reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
