ADJUSTMENTS
Quarter Window Adjustment By Symptom
To adjust the quarter window, the seats, quarter trim panel, shoulder
harness retractor and the watershield must be removed. Refer to Removal and
Installation.
The quarter window glass is nested in a metal frame which is attached to
the window carrier. The window carrier is guided by a curved pole pinned to a
support bracket which is attached to the vehicle body through another mounting
bracket. The quarter glass to door glass seal is an integral part of the
division bar attached to the lead edge of the quarter glass. Window movement is
accomplished through the window regulator assembly attachment to the carrier
guide pin.

NOTE: The following adjustments only pertain to the quarter window, assuming
that the top rails are centered and at the correct height and the door glass is
or has been properly adjusted. (Top should be lowered).
Perform preliminary adjustment Steps 1, 2 and 3 before performing
Adjustments for Symptoms A through D.
Preliminary Adjustment
- Lower window until carrier is exposed below the regulator panel.
- Remove front up-stop. Inspect for deformation. If deformed, replace and
check window alignment.

- If replacing the front up-stop corrects the noted misalignment, install the
watershield, shoulder harness retractor, quarter trim panel and rear seat as
outlined.
The adjustment procedures for the quarter window are divided into five
separate procedures according to misalignment symptoms. Determine which
procedure best describes the misalignment being corrected.
Symptom A: Gap at bottom of door glass only.

Adjustment
- Loosen the pole guide angle retention nuts and position the pole guide
angle outboard at the front edge only enough to eliminate the gap.

- Secure retaining nuts making sure the wedge adjustment angle is snug up
against the glass wedge.
- Cycle the quarter window up and down a few times, noting the position of
the division bar seal to the door glass.
- If the gap is eliminated, verify that crossover does not exist when cycling
both the quarter glass and the door glass. (To eliminate the gap, proceed with
the next step. To eliminate crossover, refer to Symptom C).
- If the gap is still evident, lower the quarter window and loosen the
carrier inboard/outboard bolts. Raise the quarter window and position the
division bar seal tight to the door glass. Lower quarter window and tighten the
carrier inboard/outboard bolts. Raise the quarter window and check the seal.

- Cycle the quarter window and door glass a number of times, verifying that
crossover does not exist. If crossover exists, refer to Symptom C.
- Install the watershield, shoulder harness retractor, quarter trim panel and
rear seat as outlined.
- Perform procedures for Symptom E.
Symptom B: Quarter glass gap entire length of door
glass.

Adjustment
- Perform preliminary adjustment.
- Lower the quarter window and loosen the carrier inboard/outboard bolts.
Raise the quarter window and position the division bar seal snug to the door
glass. Lower the quarter window and retighten the carrier inboard/outboard
bolts. Raise the quarter window and check the seal. Repeat procedure if
necessary.
- Verify that the wedge adjustment angle is snug up against the glass wedge.

- If a gap still exists between the door glass and quarter glass, the door
glass must be tilted inboard along the rear edge. Refer to Door Glass
Adjustments.
- Cycle the quarter window and door glass a number of times verifying correct
alignment and absence of crossover.
- Install the watershield, shoulder harness retractor, quarter trim panel and
rear seat as outlined.
- Perform procedures for Symptom E.
Symptom C: Quarter window crossover to the door
glass.

Adjustment
- Perform preliminary adjustment.
- Verify that the wedge adjustment angle is snug up against the glass wedge.
If not, loosen the rear pole guide angle retaining nut and move the wedge
adjustment angle outboard snug against the quarter glass wedge.
- Cycle the quarter window and door glass a number of times to check for
crossover. If the condition still exists, proceed to the next step.
- Loosen the support bracket retaining bolts and slide the support bracket
outboard while maintaining a good seal at the division bar. Cycle the quarter
window and door glass checking for crossover. If condition still exists, slide
the support bracket outboard more until the crossover ceases. If this
adjustment will not completely eliminate crossover, continue to the next step.

- Lower the quarter window and loosen the carrier in/outboard bolts. Raise
the quarter window and position the division bar seal tight to the door glass.
- In the event that all above adjustments do not completely correct the
problem, the door glass must be adjusted by tilting outboard at the rear edge.
- Cycle the quarter window and door glass a number of times to verify that
crossover will not occur.
- Install watershield, shoulder harness retractor, quarter trim panel and
rear seat as outlined.
- Perform procedures for Symptom E.
Symptom D: Door glass hits division bar when closing the
door.

Adjustment
- Perform preliminary adjustment.
- If condition still exists, adjust the rear up-stop adjustment screw
clockwise until the quarter glass and door glass are parallel. If the gap
between the quarter glass and door glass is too narrow, adjust the front
up-stop adjustment screw clockwise until the desired spacing is obtained. Cycle
the quarter window checking for repeatability. If the quarter glass is lower
than the top edge of the door glass, proceed to Step 3. If OK, proceed to Step
4.


- Lower the window and remove the front up-stop bumper. Install the bumper
and raise the quarter window, positioning as required. Lower the quarter window
and install the carrier mounting bolts. Raise the window and check alignment.
Repeat procedure if necessary to obtain correct alignment.
- Install watershield, shoulder harness retractors, quarter trim panel and
rear seat as outlined.
- Perform procedures for Symptom E.
- Touch up damaged paint on the division bar, if necessary.
Symptom E: Quarter glass changes position when top is
raised/lowered.
Adjustment
- Cycle front and quarter windows alternately to check repeatability of
alignment adjustments.
- Lower quarter window.
- Raise and latch top.
- Loosen C-pillar seal retainer. (Retainer base must be moveable).

- Raise quarter glass to full-up position.
- Set and tighten C-pillar seal retainer to 16-27 Nm (12-20
lb-ft).
- Cycle top and door/quarter windows to verify repeatability of alignment
adjustments.
