This bulletin announces a change to the procedure used in production of the rear door glass assembly. The bottom edge of the door glass is pressed into a metal channel lined with rubber. The channel attaches the door glass assembly to the window regulator. In below-freezing temperature conditions, water freezing in the channel combined with the door glass sticking to the door weatherstrip can increase chance of the glass separating from the channel when attempting to operate (lower) the window. A lubricant has been added to the rubber portion to insure the glass gets fully seated during assembly which maximizes the clamping force of the channel on the glass.
