VOIDS IN SUNROOF GLASS SPECS. FOR REPLACEMENT

SMALL VOIDS (HOLES) IN THE SUNROOF TINT FILM CAN BE CAUSED BY THE PRESENCE OF DUST ON THE GLASS WHEN THE TINT IS APPLIED. DURING NORMAL GLASS CLEANING THESE DUST SPECKS ARE WIPED OFF LEAVING A VOID (HOLE) IN THE TINT FILM. REVISED AIR PURIFICATION AND GLASS CLEANING HAS CORRECTED THIS CONDITION IN PRODUCTION. THERE IS NO SERVICE CORRECTION FOR THIS CONDITION OTHER THAN REPLACING THE PANEL. ONLY THOSE PANELS NOT MEETING THE FOLLOWING SPECIFICATIONS SHOULD BE REPLACED: 1. 1.25MM (.050") VOID - ONE FOR WHOLE GLASS PANEL 2. .75MM (.030") VOID - NO MORE THAN FOUR WIDELY SEPARATED 3. LESS THAN .75MM (.30") VOID - NO MORE THAN FIVE 4. SMALLER THAN .015MM (.0060") VOID - SEVERAL ACCEPTABLE.

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.
