While I was driving, my 2001 Pontiac Aztek Service VEHICLE Soon light came on and my thermostat meter, the needle, dropped below C. Since then, the needle will not budge below the C and yet my heater works perfectly. I went to Autozone and they had a readout that suggested that my thermostat sensor may be defective. I replaced that and things seemed fine until it did it again a few hours after replacing the sensor. Again, the heater still works. There is engine coolant as well. What else could it be?
