CAMPAIGN: WINDSHIELD AND STATIONARY GLASS RETENTION. GMC Truck S15 Pickup

CAMPAIGN NUMBER: 91C01 GROUP: 10A3 - GLASS

SUBJECT: WINDSHIELD/STATIONARY SIDE GLASS RETENTION

MODELS: 1991 S/T UTILITY/PICKUP/BLAZER/EXTENDED CAB PICKUP

** SEE BOTTOM OF CAMPAIGN FOR INFORMATION CONCERNING OTHER AFFECTED ** DIVISIONS.

DEFECT INVOLVED

GENERAL MOTORS HAS DETERMINED THAT CERTAIN 1991 S/T UTILITY/PICKUP/ EXTENDED CAB PICKUPS MAY FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD FMVSS 212"WINDSHIELD MOUNTING"

THESE VEHICLES MAY EXHIBIT POOR BOND ADHESION BETWEEN THE WINDSHIELD GLASS AND MOUNTING, WHICH COULD ALLOW THE WINDSHIELD TO SEPARATE FROM THE VEHICLE DURING A COLLISION. SHOULD WINDSHIELD SEPARATION OCCUR DURING A COLLISION, AN UNBELTED OCCUPANT COULD BE EJECTED FROM THE VEHICLE AND PERSONAL INJURY COULD OCCUR.

IN ADDITION TO THE WINDSHIELD RETENTION, IT HAS ALSO BEEN DETERMINED THAT A CUSTOMER SATISFACTION ISSUE MAY BE PRESENT REGARDING THE RETENTION OF THE STATIONARY SIDE WINDOWS (S/T UTILITY/EXTENDED CAB PICKUPS WITH NON-MOVEABLE SIDE WINDOWS).

BOTH OF THE ABOVE CONDITIONS WERE CAUSED BY IMPROPER PRIMER HAVING BEEN INSTALLED ON THE METAL SURFACE OF THE SIDE WINDOW AND WINDSHIELD OPENING, RESULTING IN LOW ADHESION TO THE METAL SURFACE. RESULTING IN LOW ADHESION TO THE METAL SURFACE.

TO CORRECT THIS CONDITION IT WILL BE NECESSARY TO REMOVE AND REINSTALL THE WINDSHIELD AND STATIONARY GLASS QUARTER WINDOWS ACCORDING TO THE INSTRUCTIONS DESCRIBED IN THIS COMMUNICATION.

THIS REPAIR MUST BE PERFORMED PRIOR TO VEHICLE SALE.

THIS BULLETIN IS NOTICE TO YOU THAT THE NEW MOTOR VEHICLES INCLUDED IN THIS CAMPAIGN MAY NOT COMPLY WITH THE STANDARD IDENTIFIED ABOVE. UNDER SECTION 108 OF THE NATIONAL TRAFFIC AND MOTOR VEHICLE SAFETY ACT, IT IS ILLEGAL FOR A DEALER TO SELL A NEW MOTOR VEHICLE WHICH THE DEALER KNOWS DOES NOT COMPLY WITH AN APPLICABLE FEDERAL MOTOR VEHICLE SAFETY STANDARD. AS A CONSEQUENCE, IF YOU SELL ANY OF THESE MOTOR VEHICLES WITHOUT FIRST PERFORMING THE COMPAIGN CORRECTION, YOUR DEALERSHIP MAY BE SUBJECT TO A CIVIL PENALTY UP TO $1,000 FOR EACH SALE.
