Removal Procedure

Important: 

• The sunroof positioning encoding (SPE) switch (3) is aligned to the drive cables. The SPE switch comes from the factory set to the window CLOSED position. A position lock pin (1) has been installed by the factory on the top of the switch. This pin must remain until after the installation of the actuator and of the SPE switch. This lock pin locks the drive gears in place and must be removed before the complete sun roof module is installed in the vehicle.
