The high speed fan is supposed to come on independently when the AC is turned on, this is normal. As for the low speed fan not coming on, It is not supposed to come on until the engine reaches normal operating temperatures. So in this case I would think the thermostat is stuck open and not allowing the engine to reach the required temperature to turn the fan on.
