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 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 such 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 Chevrolet Motor Division (see copy of owner letter included with this bulletin).

(Notification Used By Chevrolet Motor Division)

Dear Chevrolet Owner:

General Motors has determined that your 1982 Chevrolet may experience an inoperative canister purge Thermo Vacuum Switch (TVS). An inoperative canister purge TVS can adversely affect the intended function of the evaporative emission system on your vehicle.

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.

Instructions for making this correction have been sent to your Chevrolet dealer. Please contact your Chevrolet dealer to arrange a mutually satisfactory service date. The labor time necessary to perform this service is approximately twenty (20) minutes, but some 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 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 Owner Identification 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 your nearest Chevrolet Branch office either in person or by telephone. For your convenience, locations and telephone numbers of the branch offices have been attached to this letter.

If your dealer or Chevrolet Branch 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, Manufacturers Operation Division (EN-340), 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 this 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.
