Are you talking about the fan that blows air through your cabin vents? (4 position knob beneath radio). Or are you talking about your auxiliary fan (in front of the radiator?)
Case #1: Depending on the year of your car, your fan resistor or "sword" may be failing. This prevents the first 3 speeds on your fan from operating, but it will allow MAX speed (or position 4 on the knob). The resistor pack is cheap, the sword is expensive but can be repaired.
Case #2: If your auxiliary fan is only working at one speed, it might be a the fan resistor (in-line with fan circuit).
In either case, search the archives as these are common problems.
