Dale, As David pointed out some of the things that will make the fans cycle.
Also, The low pressure switch will cycle to protect the Evaporator from
freezing up if your running the blower motor on low and the AC on high. Your
recycling cold air and that is what it is supposed to do. If you want to do
some testing. Then put the mode switch on normal to draw in out side air and
maybe turn the blower motor up a notch, you should see less cycling. The
otterstat or temp switch will also be working at the same time.

This brings up another question that I had been wondering about.
My cooling fans work fine when the car heats up.  They cool it down and shut
off.
When my air conditioner is on they cycle.  I have a new otterstat switch and
fairly recently had my air conditioner charged.  I just thought it was
normal that the fans cycled like that so straighten me out.
