My 03 Mountaineer with dual ac is having an issue. When the is blower is set at the lowest speed "1" eveything is fine. However if I turn it up at say to speed 2 it goes crazy. It will blow at what I consider the correct speed for level 2 then it will all the sudden blow at full blast for 15 to 30 seconds then go back down to normal. Repeating over and over. I am leaning toward a faulty control unit. Is there anything else it could be?
