    Power Sunroof



    Diagnosis & Testing

    The power sunroof system allows the sunroof to be opened, closed, or placed in the vent position electrically by actuating a switch located in the overhead console in between the 2 reading lamps. 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 continue to operate normally with the key in the OFF position or with the key removed while the Accessory Delay System is active.

    In normal operation, 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. These models include a manual-sliding sunshade to cover the deep-tinted glass panel.

    The 2 switches located in the overhead console include the VENT switch, which is a push button type switch and opens the sunroof to the vent position only; and the OPEN/CLOSED switch, which is a rocker type switch for opening and closing the sunroof. When pressing and releasing the open button once, the sunroof should express open and the wind deflector raise. If the button is pressed a second time, the sunroof will stop in that position. Pressing and holding the CLOSED button will close the sunroof. If the close button is released, the sunroof will stop in that position.

    Motor

    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.
      1. If OK, go to Step 2.
      2.  
      3. If not OK, repair the shorted circuit or component, as required, and replace the inoperative circuit breaker.
      4.  

    2.  
    3. Partially remove the headliner to access the sunroof motor/module.
    4.  
    5. Disconnect the motor/module electrical connector.

      With the ignition switch in the RUN position, check for Battery voltage at the Accessory Relay Output terminal of the harness connector.
       
      If OK, go to Step 4.
       
      If not OK, repair the Accessory Relay Output circuit as necessary.
       

    6.  
    7. Using an ohmmeter, test for continuity between the harness connector ground circuit and a known good ground. Continuity should be present.
      1. If OK, go to Step 5.
      2.  
      3. If not OK, repair the open ground circuit as necessary.
      4.  

    8.  
    9. 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.
       

    10.  
    11. Turn the ignition switch to the OFF position.
      1. Disconnect the motor/module and sunroof switch electrical connectors.
      2.  
      3. Using an ohmmeter, check for continuity on the VENT, CLOSE, and OPEN circuits between the motor/module and sunroof switch. Continuity should be present.

        If OK, test the sunroof switch.
         
        If not OK, repair the control circuits as necessary.

    Switch

    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. The sunroof switch is a direct contact unit that is directly wired to the sunroof motor/module assembly. Repair of the power sunroof switch is not possible. If the individual components are damaged or inoperative, the switch assembly must be replaced.

    1. Remove the power sunroof switch.
    2.  
    3. Disconnect the power sunroof switch wire harness connector.
    4.  
    5. 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.
      1. If OK, go to Step 4.
      2.  
      3. If not OK, inspect the wiring harness and connectors between the motor/module and the switch for damage. Repair as necessary.
      4.  

    6.  
    7. 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.
      1. If OK, go to Step 5.
      2.  
      3. If not OK, inspect the wiring harness and the connector. Repair the ground circuit as necessary.
      4.  

    8.  
    9. Using an ohmmeter, test the continuity of the power sunroof switch in each switch position. Refer to the Power Sunroof Switch Continuity Table.
      1. If OK, inspect the wiring harness and connectors for damage. Repair as necessary.
      2.  
      3. If not OK, replace the power sunroof switch.

    Removal & Installation
    Motor

    WARNING
    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/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 the sunroof window must be in the FULLY CLOSED POSITION if possible.

    1. Before servicing the vehicle, refer to the Precautions Section.
    2.  
    3. Disconnect and isolate the negative battery cable.
    4.  
    5. Remove or disconnect the following:

      The A-pillar trim
       
      The sun visors
       
      The map lamps/mini console
       
      The sunroof switch
       
      The sunroof opening trim lace
       
      The headliner as necessary to gain access to the sunroof motor/module
       
      The motor/module wire harness connectors
       
      The motor/module attaching screws
       
      The motor/module from the sunroof housing assembly

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

    10.  

    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
     
    The glass panel has not reached its closed position
     


    NOTE
    If the initialization procedure is not carried out completely, it must be started over.

    1. Turn the ignition key to the RUN position.
    2.  
    3. Move the sunroof to the full open position.
    4.  
    5. Continuously press the OPEN button on the sunroof switch.
    6.  
    7. The sunroof will begin to move past the normal OPEN position to the Hard Stop position. It will then reverse to the normal OPEN position, also known as the Soft Stop . Once the sunroof has reversed to the Soft Stop , immediately (within 5 seconds of the sunroof stopping its travel) release the OPEN button and continuously press it again.
    8.  
    9. After a delay of 3 seconds, the sunroof will begin moving to the VENT position and then the CLOSED position. When the roof reaches the fully CLOSED position and stops, the OPEN button can be released.
    10.  
    11. The initialization procedure is now complete. Operate the sunroof in all directions to verify proper operation and alignment. Adjust as necessary.
