I looked all over the radiator and could not find a sensor mounted directly on the radiator. There are two sensors on the thermostat housing/outlet from the engine return to the radiator. I have replaced both of these sensors. One is the temperature sensor, the other is what is listed as the fan temperature switch. Replacing both of these units did not solve the issue.
I will be working on the car this afternoon to replace the 0-rings and insulators3 on the injectors and rail. I will pull the high pressure refrigerant switch connector to see if that solves the problem and will get back with you to let you know if it shut the fans off.
Hello. I found the problem. I located what I think is the fan temp switch. It is in the lower radiator below the passenger side fan. It is missing the connector plug and wire. I think the problem is solved.
Thank you for your assistance. I will leave positive feedback for you.
