So for those of you that plan to test it - here is the deal.
You can't take the voltage on the poles of the motor. You must remove the plug from the pass through in the blower motor cage. The driver's side pin will be fed 12 volts (constant) and the passenger side will have a variable voltage. The voltage should be (based on my car):
Fan speed 1: 4v, fan speed 2: 2.5v, fan speed 3: 1, fan speed 4: 0v.
Time for a blower motor.
