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.

If the motor is turning, it's the window regulator that's damaged.  The motor gear only contacts the regulator gear about an 1/4" .  Hold the window up and remove the 3 motor bolts.  You can remove the motor and inspect the gears on the motor and regulator.  With the motor out, carefully lower and raise the window to make sure its moving freely and smoothly.  

You should find the problem.  Hit the junk yard.
