Power Sunroof



Diagnosis & Testing

This vehicle has a vent, tilt, and slide power sunroof system with an express (one-touch) open feature. 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 operate normally with the key in any position while the Accessory Delay system is active.

The sunroof is electrically operated from 2 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. By 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.

Motor

Before servicing the vehicle, refer to the Precautions Section.

If the power sunroof is completely inoperative, perform the following diagnostic steps.

  1. Check the Accessory delay 30-amp Circuit breaker in the Junction Block.
    1. If it checks good, go to Step 2.
    2.  
    3. If it is not good, 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.
    1. If battery voltage is present, go to Step 4.
    2.  
    3. If battery voltage is not present, repair the Accessory Relay Output circuit as necessary.
    4.  

  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 continuity is present, go to Step 5.
    2.  
    3. If continuity is not present, 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.
    1. If 5 volts is present, go to Step 6.
    2.  
    3. If 5 volts is not present, replace the motor/module assembly.
    4.  

  10.  
  11. Turn the ignition switch to the OFF position. Disconnect the motor/module and sunroof switch electrical connectors. Using an ohmmeter, check for continuity on the VENT, CLOSE, and OPEN circuits between the motor/module and the sunroof switch. Continuity should be present.
    1. If continuity is present, diagnosis leads to the sunroof switch. Refer to Power Sunroof, Diagnosis & Testing, Switch.
    2.  
    3. If continuity is not present, repair the control circuits as necessary.
    4.

Switch

The power sunroof switch is a combination push-button and rocker switch located on the windshield header, rearward of the map lamp. 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 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.

The switch is grounded at one terminal and receives a 5 volt signal from the sunroof motor/module on the remaining 3 terminals. The switch pulls down the 5 volt reference voltage from the module signaling it to perform the desired function.

  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 and 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 connector and 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 and 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. Remove or disconnect the following:

    The negative battery cable and isolate the cable
     
    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
     

  4.  

To install:


NOTE
Before installing a new motor/module, or the original motor/module, ensure that the sunroof glass panel is in the FULLY CLOSED POSITION.

  1. Ensure that sunroof assembly is in the FULLY CLOSED position before mounting the motor/module.
  2.  
  3. Place the motor/module into position on the sunroof housing and install the attaching screws. Tighten the screws to 35 inch lbs. (4 Nm) torque.
