Removal Procedure


    Object Number: 594490  Size: SH

    Important: 

       • The Sunroof Opening Position Switch (SOPS) (3) is aligned to the drive cables. The switch comes from the factory set to the window panel CLOSED position. A position lock pin (1) has been installed on the top of the switch. The pin (1) must remain until after the installation of the actuator and of the switch. The lock pin locks the drive gears in place and must be removed before operation of the sunroof module.
       • If you reuse a Sunroof Opening Position Switch, place the sunroof window panel in the CLOSED position. Install the sunroof timing pins J 41718 . Install a position lock pin, or install 2 wires, such as the ends of a paper clip, then remove the SOPS from the sunroof module. The SOPS timing will be lost if you do not follow this procedure.

  1. Position the sunroof window panel to the closed position.
  2. Remove the sunroof module from the vehicle. Refer to Sunroof Module Assembly Replacement .

  3. Object Number: 548328  Size: SH

    Important: Before removing the SOPS from the sunroof module, the J 41718 sunroof timing pins must be installed to lock the cable/cam mechanism into position.

  4. The cable/cam mechanisms, on both sides of the sunroof window, contain a set of timing holes. These holes are aligned to the sunroof window panel in the CLOSED position. Remove the left and right side front sunroof window panel screws.
  5. Align the timing holes. Use a flat-bladed tool to push the cable/cam mechanism forward or rearward.

    Install the J 41718 sunroof timing pins into the left and right sunroof window panel screw holes.

Installation Procedure


    Object Number: 594501  Size: SH

    Important: The new SOPS comes with a position lock pin that is installed on top of the SOPS. This locks the timing gears in place. Do not remove this pin until after you have installed the SOPS and the actuator.

  1. Keeping the position lock pin in the new SOPS, position the SOPS switch over the drive cables and press down.
  2. If the SOPS does not slide into position, the ridges on the drive cable housings will not go into the grooves on the back of the SOPS. Lift each cable into the SOPS, and press down on the SOPS assembly.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
