Removal Procedure

IMPORTANT:
  • Remove the headliner. Refer to HEADLINER REPLACEMENT (PICKUP) or HEADLINER REPLACEMENT (UTILITY) or HEADLINER REPLACEMENT (EXTENDED CAB PICKUP) in Interior Trim.
  • The sunroof positioning encoding (SPE) switch is aligned to the drive cables. The SPE 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 SPE switch. This pin must remain until after the installation of the sunroof actuator and of the SPE 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 SPE 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.
  1. Move the sunroof to the closed position.
  2. Remove the sunroof glass panel. Refer to Sunroof Glass Panel Replacement .
  3. Remove the sunroof module. Refer to Power Sunroof Module Replacement .
  4. If you reuse the SPE switch, insert the position lock pin (1) in order to lock the SPE switch in the closed position.
  5. Remove the sunroof motor. Refer to Power Sunroof Motor Replacement .
  6. Disconnect the electrical connector from the SPE switch (3).
  7. Remove the screw (2) which secures the SPE switch to the sunroof module.
  8. Hold down on both of the drive cables. Lift up on the SPE switch in order to remove the switch from the sunroof module.
