I just tested one off the suggestions Thayer made. I put the ignition in the on position and played with the key a little and the fan came on. I then started the car and the fan turned off. While I had the car running I then backed off on the key counter clock wise just a bite and the fan came back on. Not sure but i think the ignition could be the problem. Is there another way to double check and make sure it is the ignition switch.
