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 two switches located on the windshield header, rearward of the map lamp.
To operate the sunroof the ignition switch must be in either the Accessory or On/Run position. One switch (vent) is
a push button type and opens the sunroof to the vent position only. The other switch (open/close) is a rocker type
for opening and closing the sunroof. Pressing and releasing the open button once the sunroof will express open and
the wind deflector will raise. If the button is pressed a second time the sunroof will stop in that position. Pressing
and holding the close button will close the sunroof. If the close button is released the sunroof will stop in that posi-
tion.

DIAGNOSIS AND TESTING

WATER DRAINAGE AND WIND NOISE DIAGNOSIS

The sliding glass panel is designed to seal water entry with a snug fit between the roof and the seal. The fit can be
checked by inserting a piece of paper between the roof and the seal. The piece of paper should have some resis-
tance when pulled out when the glass panel is in the closed position. The sunroof housing will drain off a minimum
amount of water. Excessive wind noise could result if the gap clearances are exceeded. The sunroof glass panel
may need to be adjusted. Refer to Sunroof Glass Panel Adjustment for proper procedures.

Adequate drainage is provided by a drain trough in the sunroof housing which encircles the sliding glass panel and
leads to drain hoses. If a wet headliner or other water leak complaints are encountered, before performing any

SUNROOF

23 - 249

adjustments, first ensure that the drainage system is not plugged or disconnected. Use a pint container to pour
water into the sunroof housing drain trough. If water flow is restricted, use compressed air to blow out any material
plugging the drain system. Retest system again.

To further check for a disconnected drain hose:

1. Remove A-pillar trim, sun visors, and map lamps/mini console.

2. Remove sunroof opening trim lace. (Refer to 23 - BODY/SUNROOF/OPENING TRIM LACE - REMOVAL)

3. Lower headliner as necessary to gain access to sunroof housing drain tubes. (Refer to 23 - BODY/INTERIOR/

HEADLINER - REMOVAL)

4. Repair as necessary.

5. Install headliner. (Refer to 23 - BODY/INTERIOR/HEADLINER - INSTALLATION)

6. Install sunroof opening trim lace. (Refer to 23 - BODY/SUNROOF/OPENING TRIM LACE - INSTALLATION)

DIAGNOSTIC PROCEDURES

Before beginning sunroof diagnostics verify that all other power accessories are in proper operating condition. Refer
to Sunroof Diagnostic Chart for possible causes. If not, a common electrical problem may exist. Refer to Wiring
Diagrams, in this publication for circuit, splice and component descriptions. Check the condition of the circuit pro-
tection (20 amp circuit breaker in cavity 19 of the Junction Block). Inspect all wiring connector pins for proper
engagement and continuity. Check for battery voltage at the power sunroof drive motor, refer to Wiring Diagrams, for
circuit information. If battery voltage of more than 9 volts is detected at the drive motor, proceed with the following
tests (the drive motor will not operate at less than 9 volts).

Before beginning diagnosis for wind noise or water leaks, verify that the problem was not caused by releasing the
control switch before the sunroof was fully closed. The sunroof module has a water-management system. If how-
ever, the sunroof glass is in a partial closed position, high pressure water may be forced beyond the water man-
agement system boundaries and onto the headlining.
