The pressure switch on the drier is for the a/c compressor, not the fan. The fan is actuated by a temp switch on the drier. The temp switch is usually above the pressure switch and has two wires (pigtails) that are permantly attached to the switch. (The pressure switch has two bayonet spades where wires attach.) If you jump the temp switch wires together with the ignition switch in the "Run" position, the fan should come on.
If your a/c refrigerant level is a bit low, the temp may never get high enough to trip the switch. The switch is operated by refrigerant temp, not coolant temp.
