Having a fan issue on my GTX. It has a chevy HHR fan on it. Its activated by a toggle switch and uses a relay. The problem im having is when the car is running, it will stop working for a period of time, then just turn back on by itself. Its very unpredictable, sometimes it stays off for a long while, sometimes a short while. Ive tested it when it shuts off by itself, and its getting 12.4 volts to the motor, but fan doesn't work. It only seems to do this when the car has been running for a bit. Any ideas?? Am I overlooking something? Im at the point where im thinking about buying a new fan assembly. I need my fan working, its run to hot without it. Any input would be great, thanks
