CLEANING OF UPPER INSTRUMENT PANEL SURFACES

MODELS AFFECTED: 1977-1988 ALL MODELS

This bulletin is a revision of Corporate Bulletin 85-10-20, issued in May 1985. The model years have been updated to include 1986 to 1988 models.

With the advent of longer sunlight days, comments on reflection onto the windshield of the upper instrument panel may be received. The condition of instrument panel reflection onto the windshield in direct sunlight may be aggravated by dealers and owners applying a wax or silicone base material to the pad surface. The higher gloss of such application results in a "veiling reflection" on the windshield. Advise customers and new car make ready personnel that materials containing wax or silicone should not be used to clean the instrument panel pad. A warm water and mild soap solution such as saddle soap, or an equivalent should be used whenever the instrument panel pad needs cleaning.

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.
