Power Windows: 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 regulators are removed or if excessive effort is required to operate the windows. To lubricate a door window mechanism, apply an even coating of an appropriate lithium complex polymer additive grease to the window regulator rollers, shafts and the entire length of the roller guides as illustrated by the shaded areas. See Fig 1 .
