    Important: If the sunroof was locked in the open position, it may be necessary to partially remove the copper cable tubes to pull the guide forward and expose the cable end. If the tubes are disturbed, it will be necessary to re-seal the cable tubing pass-through holes by working the sealer.

  9. Using the needle-nose pliers, lift the drive cable end out of the guide assembly and pull the cables out of the sunroof cable tubes while holding the cable tubes in position.

Installation Procedure

    Important: Cables should be replaced if they are kinked, and cables should always be replaced in pairs.

  3. Engage the cables into the guides with the cam sides of the cable ends positioned as shown in the illustration. In the proper orientation, the lobes of the cam end of the cable are aligned diagonally from the inboard top to the inboard bottom of the square-shaped guide channel.
  4. Using the installed cables, push the guides rearward to verify the proper orientation of the cam end. If the orientation is correct, the cam end will slide into the guide channel, otherwise it will hang up at the entrance to the guide channel.
