Sounds like what happened to me. I believe that the fans short out, the ac fan freezes and the main fan tends to cycle frequently. When it was in the shop getting fixed the we heard it cycling about every 20-30 seconds. The mechanic found the ac fan to be frozen. After replacing, the car ran much cooler. (later we found a shorted out alternator wire that may have caused this and other wonderful electrical problems, notice the sig) As for the dealer, Ford actually had the cheapest price on the unit. Anyway don't know if this is your same prob or not but I'd also get the wp checked while you get the rest checked to. (they have a bad habit of going even after replacement)
