James - if you see in the picture the red wire clip --that is direct to the blower motor B+ positive. The Black wire clip is direct to blower motor ground- negative. the remaining two pins are to the blower motor resistor low and medium fan. You can connect the B+ positive to either of these two pins to test the blower motor resistor.
Sorry this took so long and hope this will tell you that indeed your blower motor is ok.
The second picture is the blower motor in operation with the two jumpers, 12v supplied.
Best, mpmorris
