CAMPAIGN: JUNCTION BLOCK CORROSION - INSTALL INSULATOR

Subject: PRODUCT SAFETY CAMPAIGN 92C30 - JUNCTION BLOCK CORROSION

Model and Year: 1991-92 CHEVROLET CAPRICE POLICE CARS AND SPECIAL SERVICE WAGONS (IN CORROSION AREAS ONLY)

To: All Chevrolet Dealers

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to repair within sixty (60) days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter that is being sent to owners, the owners are being instructed to contact the Chevrolet Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1991-92 Chevrolet Caprice Police Cars (SEO 9C1) and Special Service Station Wagons (SEO 1A2) located in corrosion areas (Connecticut, Illinois, Indiana, Maine, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont and Wisconsin).

These vehicles may exhibit an electrical "ground out" condition between the 12 volt junction block and the metal inner fender skirt. This condition may cause a melted junction block, smoke, and burned underhood wiring, and may result in a disabled vehicle or a vehicle fire. This condition can occur while the vehicle is in operation, or with the vehicle parked and the ignition in the "OFF" position.

To prevent the possibility of this condition occurring, dealers are to inspect junction blocks for corrosion and install a shielding insulator under the junction block or replace the junction block in severe corrosion cases.

VEHICLES INVOLVED

Involved are certain 1991-92 Chevrolet Caprice Police Cars (SEO 9C1) and Special Service Station Wagons (SEO 1A2) located in corrosion areas and built within the following VIN breakpoints:

YEAR MODEL PLANT CODE FROM THROUGH

1991 B-Car Arlington "R" MR115652 MR152632

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.

OWNER NOTIFICATION

Police fleets/owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of fleet/owner letter included with this bulletin).

DEALER CAMPAIGN RESPONSIBILITY

All unsold new vehicles in dealers' possession and subject to this campaign must be held and inspected/repaired per the service procedure of this campaign bulletin before fleets/owners take possession of these vehicles.

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

Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owners letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

PARTS INFORMATION

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a "C.I.O." order with no special instruction code, but on an advise code (2).

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.
