Electric Window switch- 1989 Hiace supercustom

My drivers side electric window switch doesn't work, it still opens passenger side. Anyone have any idea what the part required may be?

Hi and welcome to the forum
if you put your ear to the door card can you here the motor working?
if you can it could be just a matter of lubricating the inner workings
if not it could be the motor. Also check the wireing between door and body of s.c.

P.S. check that you haven't accidentally hit the window lock switch i did it ONCE never again
