I have a 2001 Pontiac Aztek. I noticed that the temperature gauge stays below C and never rises to a normal temperature like it suppose to. The car seems to be running fine. Even after driving for a while or letting the car warm up, the gauge will stay below the C mark. Why is this & what needs to be done. Thanks.
Is this able to be done at home, the dealership, autozone or something. If done at home, where can I find a test wire & where is the switch located. Thank you.
