I'll send you the factory procedure. It will consist of two seperate procedures. The first will be removing the Regulator or Module assembly and the second will be replacing the motor.

  2. Slide the motor and housing assembly (4) onto the rail (5) and install the fastener number two (2).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  3. Rotate the motor and housing assembly to align the attachment point for attachment number one (1) and install the fastener.

    Tighten the bolts to 5 N·m (44 lb in).

  4. Install the power window module.
  5. Install the window if removed.
