Installation Procedure

    Important: Before installing the window into the door, check to see that the bottom channel is securely attached to the window. If the channel is loose, note the location of the channel on the window and then remove the channel from the window. Clean all remaining adhesive from the channel. Apply a bead of Automix Channel Bonding and Sidelite Adhesive, 3M P/N 08641, or equivalent, to the channel and install the channel onto the window. Refer to manufacturer's instructions for adhesive cure time.

  1. Install the window to the rear door.
  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.
