there are control cables that go from the heater control sliders on the dashboard down to flaps in the heater radiator housing, below the dashboard. as funky says, the control is by varying the amount of heated air that comes into the car.
the cables may not be connected properly, there is a clip that holds the outer of the cable in a fixed position, at each end (the control end and the heater housing end) if I remember correctly.
also, if the fan only works on the highest setting (ie speed) the resistor network that drops voltage at lower speeds is probably disconnected or burnt out, i suggest.
