I've replaced the stock controller of my electric fans with a wiring harness controlled by the PCM. When the truck is not moving, the fans will cycle on for about 5 or 10 seconds, go off for 5-10 seconds, then come on again. This cycle is repeated over and over and I cant figure out how to correct it. The cycling occurs when the fans are also below 170 degrees. Am I missing something here? Enclosed are the fan parameters.
