Aztek Radiator Fan Works When A C On But Not W
Engine Cooling problem
2004 Pontiac Aztek 6 cyl Front Wheel Drive Automatic 125000 miles
I recently noticed my vehicle over heating while in city traffic. Vehicle does not overheat at highway speeds. I do mostly highway driving so do not know how long this has been a problem. Coolant levels are fine in both the radiator and the reserve. The two radiator fans run when I have the A/C on but fail to run when the A/C is off. I have replaced the coolant temp sensor. I have replaced one of the fan relays. The other two fan relays are fine. The fuses are fine. All wiring is in good shape. When I drive in stop and go traffic I run the A/C as a temporary fix until I can fix the problem. I have checked with multiple part supply stores and no one can figure it out. Thank you in advanced. Please note that the thermustat was replace too.
