I would test the fan before purchasing a new one. When you start the vehicle the aux fan is activated by the ECM for the purpose of diagnosing if the fan is working properly at 20% of max speed and then shuts it off. There is also a final stage power output on the fan housing that can also make the aux fan inoperative.
