Affected: 1987-89 4 DOOR BONNEVILLE
For current models, a product enhancement was made on the Bonneville to enhance door sealing and reduce the levels of windnoise/windrush. This bulletin provides a service procedure for replacement of these scalp moldings for the current models and instructions for installation of kits on past models. In the event of a customer windnoise/windrush comment on a 1987-1989 model, Service Bulletin 89-10-20 should be followed. If sufficient reduction of windnoise/ windrush is not achieved using the items covered in 89-10-20 and windnoise/windrush is from the area between the upper door frame and body opening, then the appropriate kit for the past model vehicle may be installed after obtaining Zone/Branch authorization.
