For 1990-2009 cars

# CAMPAIGN:FOLDING REAR SEAT BACK RETENTION/INTERTIA LOCK

#### MODELS: 1983 S/T JIMMY WITH RPO AM7 FOLDING REAR BENCH SEAT

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 adequately repair within 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 a service date with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owner is being instructed to contact the nearest GMC Zone Office if their dealer does not remedy the condition within five days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed 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 some 1983 S/T Jimmy model trucks equipped with RPO AM7, Folding Rear Bench Seat. Under certain operating conditions where moderate brake stops are made, the inertia lock mechanism may not function, allowing the seat back to fold forward, and the seat to move forward.

If the rear seat is occupied, this could cause personal injury by pinning the occupant between the rear seat and the back of the front seats.

To assure positive retention of the seat back in the up position, a manually operated latch, with a positive lock and release handle, will be installed on the right hand (passenger) side of the rear seat.

VEHICLES INVOLVED

Involved are certain 1983 S/T Jimmy model trucks equipped with RPO AM7, Folding Rear

Bench Seat and identified within the following vehicle breakpoints.

Plant From Through ----- ---- ------- Pontiac SOP D0505711 Shreveport SOP D8503563

DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles subject to this campaign 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 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 the vehicle.

On vehicles involved in this campaign that have been recently sold to a retail owner, where no owner's name and address were available to GMC Truck at the time of campaign initiation, the dealer will determine the owner's name and address from the dealership sales records. Please provide this information directly on the second copy of the listing next to the applicable VIN, so that our records may be updated and the appropriate notification mailed to the owner. This second copy should then be submitted to the address listed below in the previously supplied yellow campaign envelopes.

OWNER NOTIFICATION

Owners will be notified of this campaign on their vehicles by GMC Truck (see copy of Owner Letter included with this bulletin). A listing of owner names and addresses has been furnished to the involved dealers to enable dealers to follow up with owners involved in this campaign. This listing 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 this campaign.

SERVICE PROCEDURE

2. Pivot the rear seat back forward.

3. Remove the rear seat anchor nut from both sides. Figure No. 1.

4. On the right side (Pass) only. Remove the plastic cover from the latch arm which is connected to the seat back.

5. On the right side (Pass) only. Remove the four (4) bolts attaching the latch to the seat back and bottom. Figure No. 1. Raise the rear of the seat assembly to remove latch. Support the seat in this position.

6. With the assembly raised, inspect for the presence of a flat washer on both rear seat anchor studs. Remove the washers (if present) from both sides and discard. Figure No. 2.

7. Attach the latch assembly to the seat bottom and seat back using the same bolts removed in Step 5. Tighten the bolts to the specified torque. Figure No. 1. (Note: Remove the plastic cover on the new latch to install bolts. Reinstall cover showing operating instructions of lever).

8. Lower the seat assembly positioning left hand and right hand latches over studs.

10. Test seat operation. For seat back to pivot forward, the latch must now be manually tripped on the right hand side. The left hand side remains an inertia lock. The seat will have slight movement before latch restrains it.

ADMINISTRATIVE PROCEDURE

Procedures covering this campaign are outlined in Section V of your dealership's "GMC Truck Claims Processing Manual" issued October, 1981.

Dear GMC Truck Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1983 S/T Jimmy model trucks equipped with RPO AM7 Folding Rear Bench Seat. Under certain operating conditions where moderate brake stops are made, the inertia lock mechanism may not function allowing the seat back to fold forward, and the seat to move forward. If the rear seat is occupied, this could cause personal injury by pinning the occupant between the rear seat and the back of the front seat(s).

To prevent the possibility of this condition occurring on your vehicle, please contact your GMC Truck dealer on or after the date shown below to arrange an appointment to have your vehicle corrected. Correction involves installation of a manually operated latch with a positive lock and release handle. The necessary service will be performed at no charge to you. As always, it is recommended that rear seat occupants use the seat belts. This will also minimize the possibility of the rear seat back folding forward until the new latch is installed. Instructions for making this correction have been sent to your GMC Truck dealer. It is estimated that parts will be available to your dealer on May 9, 1983.

The labor time necessary to perform this correction is approximately 20 minutes. Please allow additional time for the dealer to process your vehicle.

Your GMC Truck dealer is best equipped to obtain parts and provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not remedy this condition on that date or within five days, we recommend you contact the nearest GMC Truck Zone Office, either in person or by telephone. The zone office will assist you and the dealer in getting your vehicle corrected. The locations and telephone numbers of the Zone Offices are listed in your Owner's Manual. After contacting your dealer and the zone office, if you are still not satisfied that we have done our best to remedy this condition without charge within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, D.C. 20590, or call 800-424-9393 (Washington, D.C. residents use 426-0123). The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist him 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 owner 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 safety and 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.
