#### MODELS AFFECTED 1984 Pontiac Parisienne, Bonneville, Grand Prix and Firebird Models Equipped With 5.0L (RPO LG4, VIN Code H) or 5.0L (RPO L69, VIN Code G) Engines

#### TO: ALL PONTIAC DEALERS

General Motors has determined that certain 1984 Pontiac model vehicles may experience an inoperative canister purge Thermo Vacuum Switch (TVS). An inoperative canister purge TVS can affect the intended function of the evaporative emission system.

To prevent the possibility of this condition occurring, the canister purge TVS will be replaced on all involved vehicles.

#### VEHICLES INVOLVED

Involved are 1984 Pontiac Parisienne, Bonneville, Grand Prix and Firebird models equipped with 5.0L (RPO LG4, VIN Code H) or 5.0L (RPO L69, VIN Code G) engines produced from start-of-production 1984 model year through end-of- production 1984 model year.

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. These 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 name and address data 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).

#### DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time forward.

Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasinq the vehicle.

If there is evidence of intentional disablement of the evaporative emission system, the dealer is to notify the vehicle owner of this condition and ask if he/she wants the system restored. The cost of such restoration will be the responsibility of the owner.

Dear Pontiac Owner:

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

REASON FOR RECALL

General Motors has determined that your 1984 Pontiac may experience an inoperative canister purge Thermo Vacuum Switch (TVS). An inoperative canister purge TVS can affect the intended function of the evaporative emission system on your vehicle.

WHAT WE WILL DO

To prevent the possibility of this condition occurring, the Canister purge TVS will be replaced. 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 this service is approximately twenty (20) minutes, but additional time will be necessary to process your vehicle.

The enclosed Owner Identification Reply Card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction to your vehicle 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 so that we may update our records.

Should your dealer not schedule a service date within a reasonable time, you should contact the Pontiac Customer Assistance Center by calling: 1-800-762-2737.

If your dealer or Pontiac Central Office are unable to remedy this condition within a reasonable time, you may wish to advise the Environmental Protection Agency, at the following address: Director, Manufacturer's Operation Division (EN-340F), United States Environmental Protection Agency, 401 M Street, S.W., Washington, D. C. 20460. To ensure your full protection under the emission warranty made applicable to your vehicle by Federal Law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection test if the recall work is not accomplished.

Should your dealer find that your evaporative emission system has been intentionally disabled, you will be asked if you wish the system to be restored so that it will function as designed. The cost of such restoration will be your responsibility.

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.
