Check the outside surfaces of the radiator. Do you see a sensor or switch with 2 wires coming out of it? Disconnect that 2 wire connector....do the fans now run?

Ok.....I suspect that switch or sensor that is threaded into the radiator is faulty. I suggest you go to your favorite auto parts store and show them that switch/sensor. They should be able to ID it for you. Or...have your Auto Tech replace it. Get back to us with results.
