Installation Procedure

Important:  When installing a new SPE switch, the window must first be set to the CLOSED position. 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 window CLOSED position. These holes are located on the side opposite the rear screw hole that is used in order to mount the sunroof glass panel.

1. Align the timing holes. Use a flat-bladed tool in order to push the cable mechanism and/or cam mechanism forward or rearward.

   Insert a pin (1) 3.17 mm (0.125 in) in diameter, or insert a drill bit into each set of holes. Apply tape in order to hold each pin in place.

   Important:  The SPE 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 this pin until after you install the SPE and the actuator.

2. Keeping the position lock pin on the new SPE switch, position the switch over the drive cables, and press down.

   If the switch does not slide into position, the ridges on the drive cable housings will not slide into the grooves on the back of the SPE switch. Lift each cable up into the switch and then press down on the assembly.
