Switch Replacement - Sunroof Position Encoding System

TOOLS REQUIRED
J 41718 Sunroof Timing Pins

REMOVAL PROCEDURE

IMPORTANT:
^ The sunroof Positioning Encoding Switch (PES) (3) is aligned to the drive cables.
The YES switch comes from the factory set to the glass panel CLOSED position. A position lock pin (1) has been installed on the top of the YES switch. The pin (1) must remain until after the installation of the actuator and of the YES switch. The pin locks the drive gears in place and must be removed before operation of the sunroof module.
^ If you reuse a YES switch, place the sunroof glass panel in the CLOSED position. Install the sunroof timing pins J41718. Install a position lock pin, or install 2 wires, such as the ends of a paper clip, then remove the YES switch from the sunroof module. The YES switch timing will be lost if you do not follow this procedure.




1. Position the sunroof glass panel to the closed position.
2. Remove the sunroof module from the vehicle.

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




3. The cable/cam mechanisms on both sides of the glass contain a set of timing holes. These holes are aligned to the sunroof glass panel in the CLOSED position. Remove the left and right side front sunroof glass panel screws.
Use a flat-bladed tool to push the cable/cam mechanisms forward or rearward to align with the holes.
Install the J41718 sunroof timing pins into the left and right sunroof glass panel screw holes. Install the position lock pin or install 2 wires, such as the ends of a paper clip, to the YES switch before removal of the switch.
4. Remove the sunroof actuator.
