Can anyone out there tell me if NX have the same Window Regulator and Motor as Sentra's? What about just the motor if not the Regulator?

No, the NX uses a scissor style regulator while
the Sentra uses a cable style. Motors are
different as well. Best bet is a junkyard as the
motor is $$$ from Nissan. I heard a rumor that
the Mitsu Galant uses the same motor but have
never verified it.
