The 2013 Hyundai Elantra's cooling fan turns on when You use the AC or the engine gets hot. However, the car's ECU or "Engine Control Module" only activates the radiator's fan after receiving data generated by the car's coolant temperature sensor. On a Hyundai, the ECTS is located on the cylinder head of the engine. If it is faulty, the sensor will not detect Your vehicle's operating temperatures, and the ECU will not switch on the fan. Replacing the ECTS ranges from $130-$150 in parts and labor. Other causes of failure include a thermostat stuck in the open position; a broken motor, shorted relays or fuses or corroded wiring and connections. Getting a rapid diagnosis to prevent overheating and damage.
