Cause

1.
Remove the headliner as necessary.
2.
Jumper Pin # 1 and Pin # 8 on the sunroof express module. If more access is needed, push the module towards the motor and unlock it from the
bracket. Refer to the Illustration above.
Note:
Avoid operating the sunroof glass to the full open position. Since the limit switch has a jumper across it, there will be no indication to the
sunroof module to stop the glass at the full open soft stop. The glass can slide past the full open position, possibly damaging the sunroof
assembly and/or the roof.
3.
With the ignition ON, push the sunroof switch to the close position to fully seat the sunroof. If this action fully closes the sunroof, replace the
sunroof motor only. Refer to the Sunroof Motor Replacement below. If this action does not fully close the sunroof, go to Diagnostic Starting
Point-Roof in the service manual.
4.
Remove the jumper and re-lock the sunroof express module back into its bracket.
