Just got a 92 Legacy runs great but the drivers power window doesn't work right. Or I should say the window switch works, window motor works, but the window itself does not slide when button is pressed. Its a crammed space in the door but i think im just missing a small metal part can't see so well. I've been looking for what assembly part im missing but can't find a reference number. Help? It would go straight from motor to drivers side window asssembly.
