Yes this fan is quite the mystery for such a simple part. I would also like to point out that if the fan connecter on my car is not connected the AC condenser will not even attempt to turn on lol. I agree replacing teh thermostat should not fix this issue. I guess I'm going to also test the voltage on my power leads. I think I am correct in assuming that 12V should always be there even if the small wire is not connected.
