then i suspect the ECU is faulty. the ECU is the fan switch. the temp sensor in the stat housing tells the ECU the temp of the engine and also works the gauge in the car, when the temp reaches a predetermined value the ECU then tells the fans to work. if all other components have been properly checked and tested,and there is no faulty wiring, then other than having possibly seized fans, the ECU is the only component left... hope this helps!!
