I'm actually going to be parting my Maxima out and have the updated regulators and good window motors.
I think I know what writeup you're talking about, I'll see if I can find that.

About forgot... chances are the motor is actually good. Those very rarely go out... I can't even really think of an instance that anyone has had a motor issue. The cable in the old regulators bind really bad which can easily cause the motor to not move at all. I'd check the regulator first before buying a motor.
