Window Mechanism Lubrication
The door window mechanism should be properly lubricated to provide ease of operation. The window glass mechanism should be lubricated whenever the glass channel or window regulator is removed, or excessive effort is required to operate the windows. To lubricate a door window mechanism, apply an even coating of Multi-Purpose Grease, D7AZ-19584-AA (ESR-M1C159-A) or equivalent to the window regulator rollers, shafts and the entire length of the roller guides as illustrated by the shaded area, See Fig 1.
