CAMPAIGN: CONVERTIBLE TOP LATCH DISENGAGEMENT

Model and Year: 1989-90 CHEVROLET CAMAROS WITH CONVERTIBLE TOPS (IROC AND RS MODELS) - (G.M. BODY STYLE 67)

General Motors has determined that certain 1989-90 Chevrolet Camaros (IROC and RS models) equipped with convertible tops (G.M. body style 67) may have faulty convertible top latch handles. These latch handles may loosen which could lead to latch disengagement when a twisting load is applied. Additionally, the guide pins on the latch handles may fatigue and break. Either of these conditions may result in the front of the convertible top coming away from the windshield frame.

To correct this condition, new latch handle assemblies will be installed with integral anti-ramp stops and improved stainless steel locating pins (with flats).

VEHICLES INVOLVED

Involved are certain 1989-90 Chevrolet Camaro IROC and RS models equipped with convertible tops (G.M. body style 67) within the following VIN breakpoints:

YEAR/MODEL PLANT FROM THROUGH ---------- ----- ---- ------- 1989 F Van Nuys KL100003 KL210721

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

Either of these conditions may result in the front of the convertible top coming away from the windshield frame.

WHAT WE WILL DO

To correct this condition, new latch handle assemblies will be installed with integral anti-ramp stops and improved stainless steel locating pins (with flats). This service will be performed for you at no charge.

WHAT YOU SHOULD DO

Please contact your Chevrolet dealer as soon as possible to arrange a service date as the dealer may have to order parts in advance to perform the repair.

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.
