A/C fan

Does anyone know what might be the cause (and fix) of the A/C fan only operating on the high setting? It does this regardless if I select the A/C, heat or defrost.

Well, it would help if you explicitly identified what you are working on..

If a manual system, it's a bad blower motor resistor.
