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 in the overhead console.
The sunroof system receives battery feed through a
fuse in the Integrated Power Module (IPM), when the
ignition switch is in the RUN and ACCESSORY posi-
tions. 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 main components of the power sunroof system
are:
• The motor/module assembly
• The power sunroof glass
• The U-Frame assembly
• The power sunroof switch
• The manual-sliding sunshade
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
fuse in the Integrated Power Module (IPM), when the
ignition switch is in the RUN and ACCESSORY posi-
tions. The sunroof will operate normally with the key
in any position while the Accessory Delay system is
active.
The sunroof is electrically operated from a switch
located in the overhead console. The switch is a com-
bination rocker/push button style design that will
operate the sunroof. When pressing and releasing the
open button once, the sunroof will express open to
the comfort stop and the wind deflector will raise. If
the button is pressed a second time, the sunroof will
continue to open to full travel unless the button is
released, at which time it will stop in that position.
Pressing and holding the close button will close the
sunroof. If the close button is released before the
glass fully closes, the sunroof will stop in that posi-
tion. Pressing and holding the vent button will cause
the sunroof glass panel to tilt upward at the rear
into the “VENT” 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.
Check the condition of the circuit protection and
inspect all wiring connector pins for proper engage-
ment and continuity. For complete circuit diagrams,
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.
