Try doing what I did. First ground out your Aux. Fan switch to see if the fan works. If it spins, the fan is probably good. Or you could try hooking the fan up to a 12 volt battery and see if it spins.
I've learned that if the fan is good, but it doesn't spin at high temperatures, your switch is probably at fault.
The fan will only spin when the temperature gets too high...and the temp would definitely rise with the AC on. I've been told that the fan doesn't necessarily turn on when the AC is on, just if it gets too hot.
Try changing grounding the switch and let us know if your fan works.
