Heater/air conditioner fan only blow on high. All fans (1,2,3 and 4) were working. Then number 2 quit working. Then number 3 quit working and now only number four works.

Replace the blower motor resister. You can get them at any parts store and they are not too expensive.

Let me know if that takes care of the problem.
