(Notification used by Chevrolet motor Division)
Dear Chevrolet Owner:
This notice is being sent to inform you that Chevrolet Motor Division is conducting a recall campaign that includes your vehicle.
REASON FOR THIS RECALL
General Motors has determined that your 1984 Chevrolet may experience an inoperative canister purge Thermo Vacuum Switch (TVS). An inoperative canister purge TVS can effect the intended function of the evaporative emission control system on your vehicle.
WHAT WE WILL DO
To prevent the possibility of this condition occurring on your vehicle, the canister purge TVS will be replaced. 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. Instructions for making this correction have been sent to your dealer. The labor time necessary to perform this service is approximately twenty (20) minutes. 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 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.
Should your dealer not schedule a service date within a reasonable time, you should contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020. The Customer Assistance Center will assist you and the dealer in getting your vehicle serviced.
If your dealer or the Customer Assistance Center 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 operations 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 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.
