i have my FSM for my 95 s14 open right now. there are bolts on the door that you turn to adjust different aspects of the window. assuming its similar to the s13 (which it might not be):
A : in-out adjustment (at the top of the door where it meets the window)
B : fore aft tilt (tilts window left and right parallel to the door)
C : in-out tilt adjustment (at the top of the door)
D : up-stop adjustment (limits how far up the window goes)
E : fore aft adjustment (moves whole window left and right parallel to door)
