1. Apply multipurpose grease to the sliding surfaces of the regulator (A) where shown.

1. Install the glass and regulator in the reverse order of removal, and note these items:
   - Never use any kind other than the corrosion-resistant bolts where these special bolts are originally installed. If other bolts are used, electrolysis may accelerate corrosion around tightening points, resulting in loosening of the joints.
   - Roll the glass up and down to see if it moves freely without binding.
   - Make sure that there is no clearance between the glass and glass run channel when the glass is closed.
   - Adjust the position of the glass as necessary.
   - Check for water leaks.
   - Test-drive and check for wind noise and rattles.
   - When reinstalling the door panel, make sure the plastic cover is installed properly and sealed around its outside perimeter to seal out water.
