I have been having a rad fan relay problem. Now I can't even erase any codes from my ecm. I have already replaced the rad fan relay twice, replaced fan assembly, replaced temp sensor. Now I can't even erase trouble codes from the ecm. I am thinking it is the ecm itself melfunctioning. Any idea?

Hi:
You have replaced basically the entire system other than the ECM. Check for wiring problems. Go from the sensor to the relay and then the fan. Does the fan ever kick on? If you shake the wiring, does it kick?
