aux fan problem

My auxilary fan comes on intermitanlty, about every 30 seconds, stays on for about 15 seconds then turns off, repeat. What's wrong? What should I do first to figure out how to fix it?

It's winter -- do you have your heater set to DEFROST?

By design, the defrost setting cycles the a/c to help remove moisture from the inside of the windscreen. The a/c causes the aux fan to operate.
