Removal Procedure

IMPORTANT:

Remove the headliner. Refer to Headliner Replacement (Pickup) or Headliner Replacement (Utility) in Interior Trim.
The sunroof open position (SOP) switch is aligned to the drive cables. The SOP switch comes from the factory set to the sunroof glass panel CLOSED position. A position lock pin has been installed by the factory on the top of the SOP switch. This pin must remain until after the installation of the sunroof actuator and of the SOP switch. This lock pin locks the drive gears in place and must be removed before the complete sunroof module is installed to the vehicle.
If the SOP switch is removed for inspection, the sunroof must be in the CLOSED position. A position lock pin must be inserted. If a position lock pin is not available, place 2 wires, such as the ends of a paper clip, in the holes.

Move the sunroof to the closed position.
Remove the sunroof window. Refer to Sunroof Window Replacement (CF5) or Sunroof Window Replacement (ZRX/XTREME w/ CF5) .
Remove the sunroof control module. Refer to Sunroof Control Module Replacement .
