Radiator fan motor relies on the PCM to tell it when to turn on and off. If the motor is coming on late then most likely the PCM is faulty. There is only one coolant temp. Sensor on your vehicle and it is on the rear of the cylinder head, next to the camshaft position sensor.

If relay is not workign then the fans would either stay on or stay off, they wouldn't be able to turn on and off like you say they are.
