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 two
switches located on the windshield header, rearwardof 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 position.

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 resistance 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 clear-
ances 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 adjustments, first ensure that the
drainage system is not plugged or disconnected. Use
a pint container to pour water into the sunroof hous-
ing drain trough. If water flow is restricted, use com-
pressed 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
Sunroof Opening Trim Lace.
(3) Lower headliner as necessary to gain access to
sunroof housing drain tubes. (Refer to 23 - BODY/IN-
TERIOR/HEADLINER - REMOVAL)
(4) Repair as necessary.
DIAGNOSTIC PROCEDURES
Before beginning sunroof diagnostics verify that all
other power accessories are in proper operating condi-
tion. 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 protection (20 amp circuit breaker in cav-
ity 19 of the Junction Block). Inspect all wiring connec-
tor pins for proper engagement and continuity. Check
for battery voltage at the power sunroof controller, refer
to Wiring Diagrams, for circuit information. If battery
voltage of more than 10 volts is detected at the control-
ler, proceed with the following tests (the controller will
not operate at less than 10 volts).

SUNROOF (Continued)

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-man-agement system. If however, the sunroof glass is in a
partial closed position, high pressure water may be
forced beyond the water management system bound-
aries and onto the headlining.

CONTROL SWITCH
DESCRIPTION
Vehicles equipped with a power sunroof utilize an
sunroof control switch. On this model, the sunroof
control switch is located in the overhead console, in
between the two reading lamps. The switch is
mounted in the overhead console with four plastic
retaining tabs, molded into the switch housing.
This switch incorporates four selections of opera-
tion open, auto open, close and vent. The individual
switches in the sunroof control switch unit cannot be
repaired. If one switch is damaged or faulty, the
entire sunroof control switch unit must be replaced.
OPERATION
With the operation of the sunroof control switch,
voltage is directed to the sunroof motor, through the
switch contacts or control module. If the control
switch is depressed and held depressed the voltage
signal is controlled manually through the switch con-
tacts, so when the switch is released the sunroof
stops.
Refer to the owners manual for more information
on the operation of the sunroof switch and system.
DIAGNOSIS AND TESTING
The following test will determine if the sunroof
control switch is operating properly.
(1) Remove the overhead console from the head-
liner (Refer to 8 - ELECTRICAL/OVERHEAD CON-
SOLE - REMOVAL).
(2) Remove the sunroof control switch from the
overhead console (Refer to 23 - BODY/SUNROOF/
CONTROL SWITCH - REMOVAL).
(3) Using an ohmmeter, test the switch terminals
for proper continuity using the table below. If any ofthe terminals do not show proper continuity, replace
the sunroof control switch.

REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the overhead console from the head-
liner (Refer to 8 - ELECTRICAL/OVERHEAD CON-
SOLE - REMOVAL).
(3) Disconnect the sunroof control switch electrical
connector. Depress the connector retaining tab and
pull the connector straight out.
(4) To remove the switch from the overhead con-
sole, push on the back of the switch until it comes
free from the overhead console.
INSTALLATION
(1) Install the switch in the overhead console
assembly. Be certain the switch is securely snapped
in place.
(2) Connect the sunroof control switch electrical
connector. Be certain the switch connector is securely
snapped in place.
(3) Install the overhead console (Refer to 8 -
ELECTRICAL/OVERHEAD CONSOLE - INSTALLA-
TION).
