Ambient Air Temperature Sensor Resistance Table
WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The following table will be used to measure the resistance of the sensor and compare it with the actual ambient temperature. The mirror's temperature accuracy should be within 5° of the actual temperature. The actual temperature should not be taken from a radio station, a sign displaying the temperature, etc.
A temperature measuring tool such as a thermometer should be used. Some temperature measuring tools may be within 5° of the actual temperature. Make sure to consult the manufacturer for the accuracy of the tool. This comparison can make the mirror seem off by 5° to 10° of the actual temperature when it is not.
