Quik95SC - You mention a "blower speed control module", then you link to the "fan speed resistor" - a different part.
94MinnesotaSC - if you have the electronic climate control module (no round knobs, display for temp with push buttons), then it takes the blower speed control module. This varies - earlier Gen1s are NLA from Ford, from during-92 up it's a different part (available at the dealership and also found in other Fords such as Explorers).
If, however, you have the rotary speed control dial, then you've got the resistor - that, I don't know if it changes or not, so I'd verify.
