CAMPAIGN: INCORRECT A/C REFRIGERANT (INSPECT/REPLACE)

MODELS AFFECTED 1988 Pontiac Grand Prix With Air Conditioning (RPO C67)

General Motors has determined that certain 1988 Pontiac Grand Prix models have been produced with air conditioning systems using incorrect refrigerant. Use of this refrigerant could result in the premature failure of certain air conditioning components.

To correct this condition, the air conditioning accumulator assembly must be inspected and, as required, replaced and the system recharged on all involved vehicles before delivery to customers (reference administrative mesages dated June 10 and June 16, 1988).

VEHICLES INVOLVED

Involved are certain 1988 Pontiac Grand Prix model vehicles produced within the following VIN breakpoints:

Year Plant Beginning Up to and Including ---- ----- --------- ------------------- 1988 Fairfax JF264976 JF268673

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 the 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.

OWNER NOTIFICATION

Owners will be notified of this campaign on their vehicles by Pontiac Division (see copy of Owner Letter included with this bulletin).

Dear Pontiac Owner:

This notice is sent to inform you that Pontiac Division is conducting a recall campaign that includes your vehicle.

REASON FOR THE RECALL

General Motors has determined that certain 1988 Pontiac Grand Prix model vehicles may have been produced with air conditioning systems using incorrect refrigerant. Use of this refrigerant could result in the premature failure of certain air conditioning components.

WHAT WE WILL DO

To correct this condition, the air conditioning accumulator assembly on your vehicle must be inspected and, as required, replaced and the system recharged. This service will be performed for you at no charge.

WHAT YOU SHOULD DO Please contact your Pontiac dealer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your dealer. The labor time necessary to perform the service inspection is approximately fifteen (15) minutes, but one and one-half (11/2) hours will be required if accumulator assembly replacement is required. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary inspection/correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.

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.
