The temperature gauge on my 2001 Olds Alero stopped working yesterday.
Actually, it only moves a tiny bit and stays right over the "COLD"
level, no matter how long the car is running. However, the heat works
fine, and it didn't overheat, even though I was driving it for an hour
before I noticed the problem. So, from that I don't think that the
gauge is broken, or the thermostat is faulty. Both fans come on as soon
as I start the car. Could that be cooling the engine so much, that the
temperature stays at "COLD"? Could it be a switch probelem?
