MODELS AFFECTED: 1986-1989 BUICK LESABRES (4 DOOR H-69) 1985-1989 BUICK ELECTRA/PARK AVENUES (4 DOOR C-69)
For 1990 model year, a product enhancement was made on the 4 door LeSabre and Electra Park Avenue 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, Service Bulletin 88-10-41 should be followed. 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 installed after obtaining Zone/Branch authorization.
