Power Sunroof



Diagnosis & Testing

Refer to the list below for possible causes. Before beginning sunroof diagnostics verify that all other power accessories are in proper operating condition. If not, a common electrical problem may exist. Refer to Wiring Diagrams, in this publication for circuit, splice and component descriptions. Check the condition of the circuit protection (20 amp circuit breaker in the Junction Block). Inspect all wiring connector pins for proper engagement and continuity. Check for battery voltage at the power sunroof controller, refer to Wiring Diagrams, for circuit information. If battery voltage of more than 10 volts is detected at the controller, proceed with the following tests (the controller will not operate at less than 10 volts).

  1. Sunroof motor inoperative. Possible causes:

    Faulty control switch.
     
    Faulty circuit ground between sunroof module, control switch, and body harness.
     
    Faulty power circuit between sunroof module, control switch, and body harness.
     
    Faulty sunroof drive motor.
     
    Faulty sunroof module.
     

  2.  
  3. Audible whine when switch is depressed, sunroof does not operate. Possible causes:

    Binding cable.
     
    Faulty sunroof drive motor.
     

  4.  
  5. Audible clicking or ratcheting when switch is pressed, sunroof does not operate. Possible causes:

    Broken or worn drive cable.
     
    Worn drive motor gear.
     
    Mechanisms not synchronized.
     

  6.  
  7. Sunroof vents and opens, but does not close. Possible causes:

    Broken or disengaged trough guide
     
    Binding cable.
     
    Faulty circuit.
     
    Faulty control switch.
     
    Faulty sunroof module.
     
    Faulty drive motor.
     

  8.  
  9. Sunroof vents, but does not open. Possible causes:

    Faulty control switch.
     
    Faulty circuit.
     
    Binding cable or mechanism.
     
    Faulty sunroof module.
     

  10.  
  11. Sunroof does not vent. Possible causes:

    Faulty control switch.
     
    Faulty circuit.
     
    Binding cable or mechanism.
     
    Faulty sunroof module.
     

  12.  

Any diagnosis of the power sunroof system should begin with the use of a scan tool and the proper Diagnostic Procedures Information. The scan tool can provide confirmation that the Controller Area Network (CAN) Data Bus circuit is functional, that all of the electronic modules are sending and receiving the proper messages on the CAN Data Bus, and that the power sunroof motor/module assembly is being sent the proper hard wired output by the sunroof switch.

Removal & Installation
Motor
  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Disconnect the battery negative cable.
  4.  
  5. Remove the trim from both upper A-pillars.
  6.  
  7. Disengage the headliner wire harnesses from the retainers on each inner A-pillar and disconnect the connectors from the body wire harness connectors near the base of each A-pillar.
  8.  
  9. Remove the trim from both upper B-pillars.
  10.  
  11. Remove the trim from both upper C-pillars.
  12.  
  13. If the vehicle is so equipped, remove the overhead console from the center of the headliner near the windshield header
  14.  
  15. If the vehicle is so equipped, disconnect the electro chromic (automatic dimming) and/or the telematic (hands-free phone) mirror takeout(s) and connector(s) of the headliner wire harness from the connector receptacle(s) on the back (windshield side) of the inside rear view mirror housing.
  16.  
  17. Remove both sun visors and both visor receptacles from the headliner near the windshield header.
  18.  
  19. Remove both grab handle/coat hook/rear dome/reading lamp units from the headliner at the inner rear roof side rails.
  20.  
  21. If the vehicle is so equipped, remove the trim welt from the headliner sunroof opening.
  22.  
  23. Fold down both rear seat backs.
  24.  
  25. Recline both front seat backs.
  26.  
  27. Carefully pull the headliner downward at the windshield header far enough to disengage the spring clip retainers at each sun visor mounting location, at each visor receptacle location, and at the overhead console location.
  28.  
  29. Carefully pull the headliner downward at the inner rear roof side rails far enough to disengage the spring clip retainers at each grab handle location.
  30.  
  31. Carefully pull the headliner downward near the center of the rear roof header far enough to disengage the rear spring clip retainer.
  32.  
  33. Reach between the headliner and the roof panel from the right rear door opening to access and disconnect the sunroof jumper wire connector from the headliner wire harness sunroof take out and connector.
  34.  
  35. Carefully bow the headliner longitudinally as necessary to remove the unit through the lift gate opening.
