The fan speeds work on resistors, full speed is 12V the other speeds step down throught resistors, if a resistor breaks, that speed stops working, they are all in the small unit that bolts into the fan houseing. You need to replace the whole thing, or if you know your electronics you can replace these resistors indivdually if you know their values.
