Any DC motor only needs 2 teminals to run - a positive (+) and negitive (-). Reverse those two and the direction the motor spins changes. Based on what you're seeing, once verifed as Gunny suggests, your wiring must be switching polarity somehow.

Do you have a electrical schematic diagram of the Taurus fan motor assembly or can you draw one up from what you've got? Any relays and resistors in there? When it was installed in a Taurus, was the fan motor grounded to the car's body/engine, or was it a floating ground due to it being mounted on rubber isolators/plastic? We'll need this type of info to steer you in the right direction.
