Jeep Liberty KJ. Manual - part 171

REMOVAL

NOTE: The sunroof system is timed from the factory so that the motor/module shuts off automatically when
the sunroof window reaches a certain position. Extreme care must be taken when removing the motor/mod-
ule 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 the sunroof window must be in
the FULLY CLOSED POSITION if possible.
If glass panel is not in the fully closed position and the motor/module is removed or inoperative, (Refer to
8 - ELECTRICAL/POWER TOP/MOTOR - STANDARD PROCEDURE).

1. Disconnect and isolate the negative battery cable.

2. Remove A-pillar trim (Refer to 23 - BODY/INTERIOR/A-PILLAR TRIM - REMOVAL).

3. Remove sun visors (Refer to 23 - BODY/INTERIOR/SUN VISOR - REMOVAL).

4. Remove map lamps/mini console, (Refer to 8 - ELECTRICAL/LAMPS/LIGHTING - INTERIOR/READING LAMP -

REMOVAL).

5. Remove the sunroof switch, (Refer to 8 - ELECTRICAL/POWER TOP/SWITCH - REMOVAL).

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

7. Remove headliner as necessary to gain access to sunroof motor/module. (Refer to 23 - BODY/INTERIOR/HEAD-

LINER - REMOVAL).

8. Disconnect the motor/module wire harness connectors.

9. Remove the motor/module attaching screws.

10. Remove motor/module from the sunroof housing assembly.

INSTALLATION

NOTE: Before installing a new motor/module or the original motor/module ensure that the sunroof glass
panel is in the FULLY CLOSED POSITION. If sunroof glass panel is not in the FULLY CLOSED POSITION,
(Refer to 8 - ELECTRICAL/POWER TOP/MOTOR - STANDARD PROCEDURE).

1. Ensure that sunroof assembly is in the FULLY CLOSED position before mounting the motor/module. If not in the

fully closed position (Refer to 8 - ELECTRICAL/POWER TOP/MOTOR - STANDARD PROCEDURE).

2. Place motor/module into position on the sunroof housing and install attaching screws. Tighten the screws to 3.5

N·m (31 in. lbs.) torque.

3. Connect the motor/module, and sunroof switch wire connectors.

4. Install sunroof glass panel (Refer to 23 - BODY/SUNROOF/GLASS PANEL - INSTALLATION).

5. Connect the battery negative cable.

6. Perform the motor/module initialization procedure, (Refer to 8 - ELECTRICAL/POWER TOP/MOTOR - STAN-

DARD PROCEDURE - MOTOR/MODULE INITIALIZATION).

7. Verify sunroof operation and alignment, and adjust as necessary. (Refer to 23 - BODY/SUNROOF/GLASS

PANEL - ADJUSTMENTS).

8. Disconnect and isolate battery negative cable.

9. Installing the headliner (Refer to 23 - BODY/INTERIOR/HEADLINER - INSTALLATION).

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

11. Install the sunroof switch, (Refer to 8 - ELECTRICAL/POWER TOP/SWITCH - INSTALLATION).

12. Install the map lamps/mini console, (Refer to 8 - ELECTRICAL/LAMPS/LIGHTING - INTERIOR/READING

LAMP - INSTALLATION).

DESCRIPTION

The power sunroof switch is a combination push-but-
ton and rocker switch located in the overhead console
(1) positioned between the two reading lamps (4). The
switch is mounted in the overhead console with four
plastic retaining tabs, molded into the switch housing.
The sunroof switch is a direct contact unit that is
directly wired to the sunroof motor/module assembly.
The sunroof switch performs the following functions:

•

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 inoperative 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 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 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.

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 signaling it to perform the
desired function.

For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wir-
ing 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

SUNROOF SWITCH

1. Remove the power sunroof switch, (Refer to 8 - ELECTRICAL/POWER TOP/SWITCH - REMOVAL).

2. Disconnect the power sunroof switch wire harness 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 connector. 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 in each switch position. Refer
to the POWER SUNROOF SWITCH CONTINUITY
TABLE . If OK, inspect the wiring harness and con-
nectors for damage and repair as necessary. If not
OK, replace the power sunroof switch, (Refer to 8 -
ELECTRICAL/POWER

TOP/SWITCH

REMOVAL).
