Door Glass Adjustment ^?
9.2.01.8 - Door Glass Adjustment
The door glass can be adjusted in three planes. Lateral, Up and Down, and Front to Rear. It is advisable however
to avoid forward and rearward adjustment if possible,
as
this will affect the height and overall position of
the
glass
relative to the seals. Use this adjustment only to correct serious misalignment.
Lateral Adjustment
Remove the door trim pad. Partially lower the window to allow access to the glass channel mounting bracket (Fig
6-A). Slacken off the four nuts to allow lateral adjustment. Move the glass to the desired position and tighten the

nuts.
Close the
window
and
recheck the alignment.
Repeat the
adjustment until
the
optimum alignment
is
achieved.
Refit the door trim pad.
Upward Adjustment
Remove the door trim pad. Slacken off the regulator locknut (Fig 6-B). With the door
closed,
operate the window
to the fully closed position and tighten the locknut. Refit the door trim panel.
Front to Rear Adjustment
Remove the door trim pad. Partially lower the window to allow access to the glass channel mounting bracket (Fig

6C).
Slacken
the
four
screws
to allow
