Inside Ambient Air Temperature Incorrect Or Does Not Vary
- Turn ignition on. Ensure "INSIDE" temperature is displayed. If not, push "TEMP" button one time. Record inside ambient air temperature displayed. Compare that temperature with a thermometer. Difference should be no more than 2°F.
- If temperature varies, remove left front speaker cover. Disconnect negative battery cable. Unplug cluster harness connector. Measure resistance between pins C (Dark Green wire) and U (Black wire) of cluster harness connector. Compare readings to Temperature Sensor Resistance chart.TEMPERATURE SENSOR RESISTANCE
