It may be somewhat difficult to diagnose wind noise or water leak on some 1988 Celebrity cars built at the ste. Therese Plant. The condition may be caused by a skip in the urethane at the upper left corner of the windshield. This may or may not cause a water leak. It may also cause a wind noise that sounds like it is in the upper middle of the glass when it is actually at the upper left corner. Repair in the usual manner.
This sealing operation condition occurred only the week of November 16, 1987.
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.
