For more on marking an answer as the "Best Answer", please visit our FAQ.The ECU on this car controls the rad fan(s)
The ECU senses the temp output from the thermal sensor in the cyl. head.
If the ambient temperature is over a preset amount, and the A/C is on, the fans will run.
If the ECU senses a rise in coolant temp to approx 90degC, the fans will run
Right .. that's that one cleared up.
