STANDARD PROCEDURE

STANDARD PROCEDURE - POWER SUNROOF
TIMING

NOTE: Perform the timing procedures if any of the
following conditions exist:

• Glass skewed in the channel

• One side of the glass dropping before the other

while moving from “VENT” to “CLOSE”

• Glass reversing direction when closing the sun-

roof

• Glass will not close or may stop at the wrong

location

• The glass may over travel the “OPEN” position

and stall the motor

• The glass may over travel the “CLOSE” position

and stall the motor

NOTE: The timing of motor/module and the sunroof
assembly play a critical roles in the proper function
of the sunroof. If the motor/module is removed and
the sunroof glass or cables are moved the sunroof
module will have to be timed. REFER to the follow-
ing procedure for the necessary steps.

(1) Perform the motor/module re-initialization pro-

cedure, (Refer to 8 - ELECTRICAL/POWER TOP/
MOTOR - STANDARD PROCEDURE).

(2) Remove the motor/module, (Refer to 8 - ELEC-

TRICAL/POWER TOP/MOTOR - REMOVAL).

(3) Remove sunroof glass panel (Refer to 23 -

BODY/SUNROOF/GLASS PANEL - REMOVAL).

(4) Now place both right and left arms in the

closed position. Using a screwdriver, push the plastic
cable all the way forward in the track until the glass
mounting arm drops into the closed position.

(5) Repeat this on the other side.
(6) To verify correct timing, there is an 1/8 inch

hole in the cable ramp that must be aligned with the
front glass mounting screw hole.

(7) Using an awl, verify alignment of both right

and left timing holes. The tracks will now be timed
to the fully closed position.

(8) Install the motor/module (Refer to 8 - ELEC-

TRICAL/POWER TOP/MOTOR - INSTALLATION).

(9) Install the sunroof glass panel, (Refer to 23 -

BODY/SUNROOF/GLASS

PANEL

INSTALLA-

TION).

(10) Perform

the

motor/module

re-initialization

procedure, (Refer to 8 - ELECTRICAL/POWER TOP/
MOTOR - STANDARD PROCEDURE).

STANDARD PROCEDURE - RE-INITIALIZATION

NOTE: If for some reason the sunroof is not oper-
ating normally it may be necessary to re-initialize
the sunroof assembly. This procedure should be
attempted prior to any diagnosis of the sunroof
system.

NOTE: The re-initialization procedure is not com-
plete if any one of the following conditions occurs
before the re-initialization procedure is completed:

• The sunroof switch is not held in the CLOSE

position.

• The ignition or battery power is lost.

• The glass panel has not reached its closed posi-

tion.

NOTE: if the re-initialization procedure is not car-
ried out completely, it must be started over.

(1) Cycle the sunroof to full “VENT” position.
(2) Once the sunroof is in the full “VENT” position,

press and continuously hold the “CLOSE” button on
the sunroof switch.

(3) After a delay of 10 seconds the sunroof will

begin to move past the normal “VENT” position to
the hard stop position. It will then reverse to the
normal “VENT” position also known as the soft stop.
Once the sunroof has reversed to the soft stop,
immediately (within 5 seconds of stopping travel)
release the “CLOSE” button and continuously press
it again.

(4) After a delay of three seconds the sunroof will

begin moving to the “OPEN and then “CLOSED posi-
tion. When the roof reaches the fully “CLOSED” posi-
tion and stops the close button can be released.

The Re- initialization procedure is now complete.

Operate the sunroof in all directions to verify proper
operation.

STANDARD PROCEDURE - INITIALIZATION

NOTE: This procedure should be attempted any
time a new motor/module is installed in the sunroof
assembly. It must be performed on initial vehicle
power up to be successful.

NOTE: The initialization procedure is not complete
if any one of the following conditions occurs before
the initialization procedure is completed:

• The sunroof switch is not held in the CLOSE

position.

• The ignition or battery power is lost.

out completely, it must be started over.

(1) Turn the ignition key to the “RUN” position.
(2) Continuously press the “CLOSE” button on the

sunroof switch.

(3) The sunroof will begin to move past the normal

“VENT” position to the hard stop position. It will
then reverse to the normal “VENT” position also
known as the soft stop. Once the sunroof has
reversed to the soft stop, immediately (within 5 sec-
onds of stopping travel) release the “CLOSE” button
and continuously press it again.

(4) After a delay of three seconds the sunroof will

begin moving to the “OPEN and then “CLOSED posi-
tion. When the roof reaches the fully “CLOSED” posi-
tion and stops the close button can be released.

The initialization procedure is now complete. Oper-

ate the sunroof in all directions to verify proper oper-
ation.

REMOVAL

NOTE: The sunroof system is timed from the fac-
tory so that the motor/module shuts off automati-
cally when the sunroof window reaches a certain
position. Extreme care must be taken when remov-
ing the motor/module from the sunroof assembly or
this timing may be thrown off causing damage to
the sunroof system. Anytime the motor/module
needs to be removed from the sunroof assembly

DESCRIPTION

The power sunroof switch is a combination push-

button and rocker switch located in the overhead con-
sole in between the two reading lamps, (Fig. 1). The
switch is mounted in the overhead console with four
plastic retaining tabs, molded into the switch hous-
ing. The sunroof switch is a direct contact unit that
is directly wired to the sunroof motor/module assem-
bly. The sunroof switch performs the following func-
tions:

• Power sunroof open

• Power sunroof auto open

• Power sunroof closed

• Power sunroof vent

The power sunroof switch cannot be repaired. If

the individual components are damaged or inopera-
tive the switch assembly must be replaced, (Refer to
8

ELECTRICAL/POWER

TOP/SWITCH

REMOVAL).

OPERATION

The sunroof is electrically operated from two

switches located on the windshield header, rearward
of the map lamp. The “VENT” switch is a push but-
ton 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.

The switch is grounded at on terminal and receives

a 5 volt signal from the sunroof motor/module on the
remaining three terminals. The switch pulls down
the 5 volt reference voltage from the module signal-
ing it to perform the desired function.

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.

DIAGNOSIS AND TESTING

For complete circuit diagrams, refer to the

(1) Remove the power sunroof switch, (Refer to 8 -

ELECTRICAL/POWER TOP/SWITCH - REMOVAL).

(2) Disconnect the power sunroof switch wire har-

ness connector.

(3) With the ignition key in the “RUN” position

check for 5 volts on the “OPEN”, “CLOSE” and
“VENT” circuits of the sunroof switch harness connec-
tor. If OK, go to Step 4. If not OK, inspect the wiring
harness and connectors between the motor/module and
switch for damage and repair as necessary.

(4) With the ignition key in the “OFF” position

check for continuity between the ground circuit of the
sunroof switch harness connector and a known good
ground. Continuity should be present. If OK, go to
Step 5. If not OK, inspect the wiring harness and
connector and repair the ground circuit as necessary.

(5) Using an ohmmeter, test the continuity of the

power sunroof switch (Fig. 2) in each switch position.
