Installation Procedure

    IMPORTANT: The cable mechanisms and/or the cam mechanisms, on both sides of the glass, contain a set of timing holes. These holes are aligned in the CLOSED position of the sunroof glass panel. These holes are located on the side opposite the rear screw hole, which is used in order to mount the sunroof glass panel. When installing a new sunroof open position (SOP) switch, set the sunroof glass panel to the CLOSED position.
  1. Use a flat-bladed tool if you adjust the cable mechanism and/or the cam mechanism in order to align the cable and/or the cam timing holes.

    When the timing holes are aligned, insert a pin with diameter 0.0317 mm (1/8 in) or a drill bit (1) into each set of the timing holes. Use tape in order to hold each pin in place.

    2. IMPORTANT: The SOP switch comes from the factory with a position lock pin that is installed on top of the switch. This locks the timing gears in place. Do not remove the position lock pin until after the SOP switch and the actuator are installed.
  2. Keeping the position lock pin on the new SOP switch, align the switch over the drive cables.

  3. Apply pressure to the SOP switch until the switch is completely seated.

    If the switch does not slide into position, the ridges on the drive cable housings will not go into the grooves on the back of the SOP switch. Lift each cable into the switch, and press down on the assembly until the assembly is completely seated.
