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 in the overhead console. 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. Also, by pressing the close button the sunroof will close automatically.

POWER SUNROOF

This vehicle has a vent, tilt and slide power sunroof system with express (one-touch) open/close feature. The sunroof system receives battery feed through the "sunroof" relay and a 25 amp mini fuse located in the Totally Integrated Power Module (TIPM). 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 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 releasing the close button once will express close the sunroof. If the close button is pressed a second time during the express close operation the sunroof will stop in that position.

DIAGNOSTIC PROCEDURES

Before beginning sunroof diagnostics verify that all other power accessories are in proper operating condition. Refer to SUNROOF DIAGNOSIS CHART for possible causes. If not, a common electrical problem may exist. Refer to SYSTEM WIRING DIAGRAMS article for circuit, splice and component descriptions. Check the condition of the circuit protection (20 amp circuit breaker in the Totally Integrated Power Module (TIPM)). Inspect all wiring connector pins for proper engagement and continuity. Check for battery voltage at the power sunroof drive motor. Refer to SYSTEM WIRING DIAGRAMS article for circuit information. If battery voltage of more than 9 volts is detected at the drive motor, proceed with the following tests (the drive motor will not operate at less than 9 volts).

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

SWITCH-SUNROOF

SUNROOF SWITCH📷 1

The power sunroof switch (2) is a combination push-button and rocker switch module mounted in the overhead console assembly (1). 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 (back of switch pushed) Power sunroof express open (back of switch pushed and released) Power sunroof closed (front of switch pushed) Power sunroof express closed (front of switch pushed and released) Power sunroof vent (switch center button pushed)

The power sunroof switch is part of the overhead console assembly and cannot be serviced separately. If the switch is damaged or inoperative the overhead console assembly must be replaced. Refer to REMOVAL .

SUNROOF SWITCH📷 1

The sunroof is electrically operated from two switches located in the headliner on the courtesy/reading lamp assembly. The power sunroof switch is hard wired to the sunroof motor/module assembly. 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 releasing the close button once will express close the sunroof. If the close button is pressed a second time during the express close operation the sunroof will stop in that position.

The switch is grounded at one 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 SYSTEM WIRING DIAGRAMS article. The wiring 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.

SUNROOF SWITCH📷 1

1. Remove the overhead console, refer to 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 POWER SUNROOF SWITCH CONTINUITY TABLE. If OK, inspect the wiring harness and connectors for damage and repair as necessary. If not OK, replace the overhead console assembly, refer to
