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.
