Inside Temperature Sensor
WARNING: This page is about a different car, the 2002 Cadillac Seville. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition off. Disconnect inside air temperature sensor 4-pin connector. Measure resistance between sensor terminals "A" (Dark Green wire) and "D" (Yellow wire) at various temperatures. See INSIDE TEMPERATURE SENSOR RESISTANCE SPECIFICATIONS table. If resistance is not as specified, replace temperature sensor.
