SUNROOF
DESCRIPTION
WARNING: Keep fingers and other body parts out
of sunroof opening at all times.
The sunroof features a power sliding glass panel
and a sunshade which can be manually positioned
anywhere along its travel, rearward of glass panel
front edge.
The sunroof is electrically operated from a switch
located on the mini overhead console. To operate the
sunroof the ignition switch must be in the On/Run
position. The sunroof has both manual and Express
Open modes of operation when opening. To open the
sunroof in the Express Open mode, the switch is
pressed rearward for less than1 second.This causes
the sunroof glass to automatically retract and stop at
a position slightly forward of full open that reduces
low speed wind buffeting. The sunroof can also be
opened manually by pressing and holding the switch
rearward. Once the switch is held reward for more
than1 second,the glass will retract in the manual
mode. Releasing the switch at any time during travel
will cause the sunroof to stop at the current position.
To close the sunroof from an open position, the
switch must be pushed forward and held until the
sunroof glass comes to a complete stop. Releasing the
switch at any time in this mode will cause the sun-
roof to stop at the current position.
To vent the sunroof from the closed position, the
switch is pushed forward and held. Releasing theswitch at any time during travel will cause the sun-
roof to stop at the current vent position. To reach the
fully vented position, continue to hold the switch for-
ward until vent motion stops. To close the sunroof
from the vent position, push and hold the switch
rearward until the glass comes to a complete stop.
DIAGNOSIS AND TESTING - SUNROOF
CAUTION: The sunroof motor is only to be powered
through the vehicle battery and vehicle wire har-
ness. Applying power to the sunroof motor leads
will cause failure of the sunroof control unit.
Before beginning sunroof diagnostics verify that all
other power accessories are in proper operating con-
dition. Refer to Sunroof Diagnostic Chart for possible
causes. If not, a common electrical problem may
exist. Refer to Group 8W, Wiring Diagrams, of this
publication for circuit, splice and component descrip-
tions. Check the condition of the circuit protection
(20 amp high current fuse (battery feed) located in
the Power Distribution Center (PDC). Check the
cover of the PDC for location of the fuse. Check for
correct operation of the sunroof delay relay. Inspect
all wiring connector pins for proper engagement and
continuity. Check for battery voltage at battery and
ignition pins of the power sunroof express module
wiring connector. Refer to Group 8W, Wiring Dia-
grams, for circuit information. The controller will not
operate at less than 10 volts. Check the ground at
the sunroof express module.
Before beginning diagnosis for wind noise or water
leaks, verify that the problem was not caused by
23 - 96 SUNROOFWJ

releasing the control switch before the sunroof was
fully closed. The sunroof module has a water-man-
agement system. During washing high-pressure
water may be forced between the glass panel seal
and the roof opening. Normally this water will drain.
However, when some type of drying blower system is
used, like those found in automatic car washes, thewater may not have a chance to drain before the
blower forces air between the seal and the roof open-
ing. This causes the water to blow over the edge of
the module and onto the headlining.
Refer to (Fig. 1) Sunroof Assembly for exploded
view of the sunroof.
SYMPTOM STEP POSSIBLE CAUSE
Sunroof squeaks when
opening/closing.1 Identify if the cause is a seal squeak. If seal is worn, replace the
seal.
2 Check seal compression for uniformity in opening, If not uniform,
glass is not centered in opening.
3 Re-center glass by repositioning module in opening.
4 Identify if mechanism squeaks.
5 Check for lubrication, re-lube if necessary.
6 Check for dirt/debris in tracks, clean and re-lube.
7 Identify if motor squeaks, replace the motor.
Water leaks into the vehicle. 1 Check for a good connection at the drain tubes, re-connect where
needed.
2 Check for plugged/pinched hoses throughout.
3 Adjust the glass panel. Refer to glass panel adjustments in this
section.
4 Check seal for wear/damage, replace glass as necessary.
Motor inoperative. 1 Check connectors at the motor, switch, control module and power
source.
2 Check for defective control module, replace if necessary.
3 Replace the motor.
Motor noise when opening/
closing.1 Identify if motor noise, replace motor.
2 Insure noise is from the motor and not cables, (cable ratcheting).
Grinding noise when opening/
closing.1 Identify if the motor is grinding, replace motor.
(Mechanism noise, scraping.) 2 Check for lubrication in tracks and mechanism, re-lube if
necessary.
3 Check for dirt/debris in tracks, clean and re-lube.
(Cable ratcheting.) 4 Cables ratchet at the motor pinion; mechanism jammed, fix
mechanism and replace cables and motor bracket.
Wind noise when sunroof fully
closed.1 Check seal compression for uniformity in opening, If not uniform,
glass is not centered in opening.
2 Glass not adjusted flush to roof. Refer to glass panel adjustments
in this section.
3 Mechanism not fully closed.
A) Motor out of time, re-time motor/mechanism. Refer to glass
panel adjustments in this section.
B) Cable ratcheting, replace cables and motor bracket.
4 Seal worn, replace glass.
Sunroof will not open/close. 1 Check switch and switch connection.

SYMPTOM STEP POSSIBLE CAUSE
2 Check mechanism for binding (result of forcing the glass closed/
broken components).
3 See motor inoperative above.
Sunroof9rattles9, anytime,
closed/open.1 Loose attachment screws (module), re-fasten and adjust module.
2 Loose glass panel, re-fasten and adjust glass panel.
3 Loose drain channel, refasten/secure to repair.
4 Broken mechanism, replace the sunroof assembly module.
5 Mechanism not fully closed.
A) Motor out of time, re-time motor/mechanism. Refer to glass
panel adjustments in this section.
B) Cable ratcheting, replace cables and motor bracket.
6 Check for sunshade out of track or for sunshade broken slide
block.
7 Loose wind deflector. Replace if broken.
8 Loose wind deflector spring. Replace if loose.
Sunshade squeaks/rattles,
anytime.1 Sunshade slide blocks out of track(s), put back in tracks.
-OR- 2 Missing felt pads on the drain channel, add felt pads.
Sunshade force high/low or
binding during operation.3 Felt on the drain channel rolling off, (sunshade rubs on adhesive),
replace felt pads.
4 Slide block binding in sunshade, free-up slide block by actuating a
couple times, grease slide block(s) and spring(s).
5 Broken slide block in sunshade, replace slide block.
6 Slide block spring missing, replace spring and slide block.
7 Sunshade interference with drain channel or trim welt, replace trim
welt and/or sunshade.
Motor/sunroof control module
operation: Auto open doesn't
work, or doesn't stop at closed
position.1 After power disconnect or replacement, sunroof module has to
complete on full cycle to program the sunroof control module. Full
cycle = close > open > close > vent > close.
