If the dial is working then i would suggest that there is a fault with the resistor for the motor.

sounds like as stef123 says....resistor pack for the blowers

Yes, you need a new resistor pack. Setting 4 bypasses the resistor pack totally, which is why that setting works. I've had this problem on both my Focuses

One quick fix is to remove the resistor and solder a wire onto each end of the little diode.
