DESCRIPTION
WARNING: Keep fingers and other body parts out
of sunroof opening at all times.
The power sunroof system allows the sunroof to be
opened, closed or placed in the vent position electri-
cally by actuating a switch located in the overhead
console in between the two reading lamps. The sun-
roof system receives battery feed through a 30 amp
circuit breaker in the junction block. The sunroof sys-
tem power is supplied when the ignition switch is in
the RUN and ACCESSORY positions. The sunroof
will continue to operate normally with the key in the
OFF position or with the key removed while the
Accessory Delay System is active.
The sunroof glass panel tilts upward at the rear for
ventilation and slides rearward under the roof when
open. The panel seals flush with the roof in the
closed position to eliminate wind noise. The sunroof
includes a manual-sliding sunshade to cover the
deep-tinted glass panel.
The sunroof is electrically operated from two
switches located in the overhead console in between
the two reading lamps. The “VENT” switch is a push
button type switch and opens the sunroof to the vent
position only. The other switch “OPEN/CLOSED” is a
rocker type switch for opening and closing the sun-
roof. 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 hold-
ing the close button will close the sunroof. If the
close button is released the sunroof will stop in that
position.
OPERATION
This vehicle has a vent, tilt and slide power sun-
roof system with express (one-touch) open feature.
The sunroof system receives battery feed through a
30 amp circuit breaker in the junction block. The
sunroof system power is supplied when the ignition
switch is in the RUN and ACCESSORY positions.
The sunroof will operate normally with the key in
any position while the Accessory Delay system is
active.
The sunroof is electrically operated from two
switches located in the overhead console in between
the two reading lamps. The “VENT” switch is a push
button type switch and opens the sunroof to the vent
position only. The other switch “OPEN/CLOSED” is a
rocker type switch for opening and closing the sun-
roof. 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 hold-
ing the close button will close the sunroof. If the
close button is released the sunroof will stop in that
position.
DIAGNOSIS AND TESTING
SUNROOF
Refer to SUNROOF DIAGNOSIS CHART for pos-
sible causes. Before beginning sunroof diagnostics
verify that all other power accessories are in proper
operating condition. If not, a common electrical prob-
lem may exist.

refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.

DIAGNOSIS AND TESTING -
For complete circuit diagrams, refer to the
appropriate wiring information. The wiring infor-
mation includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
If the power top is completely inoperative perform
the following diagnostic steps.
(1) Check the Accessory delay 30 amp Circuit
breaker in the Junction Block. If OK, go to Step 2. If
not OK, repair the shorted circuit or component as
required and replace the inoperative circuit breaker.
(2) Partially remove the headliner to access the
sunroof motor/module.
(3) Disconnect the motor/module electrical connec-
tor. With the ignition switch in the “RUN” position
check for Battery voltage at the Accessory Relay Out-
put terminal of the harness connector. If OK , go to
Step 4. If not OK repair the Accessory Relay Output
circuit as necessary.
(4) Using an ohmmeter test for continuity between
the harness connector ground circuit and a known
good ground. Continuity should be present. If OK go
to Step 5. If not OK, repair the open ground circuit
as necessary.
(5) Turn the ignition switch to the “OFF” position.
Reconnect the motor/module electrical connector.
With the ignition switch in the “RUN” position check
for 5 volts on the “VENT”, “CLOSE” and “OPEN”
control circuits at the back side of the motor/module
connector. If OK, go to Step 6. If not OK replace the
motor/module assembly, (Refer to 8 - ELECTRICAL/
POWER TOP/MOTOR - REMOVAL).
(6) Turn the ignition switch to the “OFF” position.
Disconnect the motor/module and sunroof switch
electrical connectors. Using an ohmmeter check for
continuity on the “VENT”, “CLOSE” and “OPEN” cir-
cuits between the motor/module and sunroof switch.
Continuity should be present. If OK, (Refer to 8 -
ELECTRICAL/POWER TOP/SWITCH - DIAGNOSIS
AND TESTING) for diagnosis of the sunroof switch.
If not OK, repair the control circuits as necessary.
