For 1990 model year, a product enhancement was made on the 4 door Eighty-Eight and Ninety-Eight models 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 1990 model and instructions for installation of kits on past models. In the event of a customer windnoise/windrush comment on a 1985-1989 model, refer to Oldsmobile Service Guild Articles published in October 1988 (page 10-15) and November 1988 (page 22-30). If sufficient reduction of windnoise/windrush is not achieved using the items covered in 88-10-41 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 authorized for installation.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
