1997 Cadillac DeVille Question: Heater blower motor not coming on

 

Question

I pulled the blower motor and plugged it back in and it does not turn, there is electrical current in one of the wires that connect to the motor, I was able to get the motor to jog about a 1/4 of a turn by putting jumper wires to it, by doing this a second time it reversed rotation and turned about 1/4 of a turn in the oppisite direction.
Does it mean the motor is bad?

    Sounds like a bad motor. You should be able to turn the motor by hand very easily, if it is not turning or feels rough, replace the motor.

    The motor turns freely by hand with no roughness or noise at all. How can I test the heater motor?
    UPDATE; Found used heater motor for $45, salvage yard let me take and plug it in and return if it didn't work, it did work and I now have the heater working back to normal.
