CAMPAIGN: FRONT SEAT BACK RECLINER ATTACHMENT. GMC Truck GMC C Pickup

SUBJECT: FRONT SEAT BACK RECLINER ATTACHMENT -----------------------------------

MODELS: 1993 - 1994 C/K EXTENDED CAB TRUCKS -----------------------------------

THIS BULLETIN CANCELS AND REPLACES BULLETIN 94-C-62 ISSUED MARCH, 1996. ALL COPIES OF 94-C-62 SHOULD BE DESTROYED.

THE WARRANTY INFORMATION SECTION HAS BEEN REVISED TO ADD ADDITIONAL V-OPERATION NUMBERS. THE SERVICE PROCEDURE HAS BEEN REVISED TO ADDRESS THE ISSUE OF LEATHER SEATS AND NON-PRODUCTION SEATS.

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 appointments with owners and to repair their vehicles 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 Pontiac-GMC Division Consumer Relations Office if the 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 decided that a defect, which relates to motor vehicle safety, exists in CERTAIN 1993-94 C/K extended cab trucks equipped with front high-back bucket seats (A95) or 60/40 split bench seats (AE7). These seats may have the seat recliner to seat frame attaching bolts loosen, fatigue, and fracture, allowing the seat back to suddenly recline. If this was to occur on the driver's seat, this could lead to sudden loss of vehicle control and crash without prior warning. The loosening of the bolts can be attributed to foam and/or fabric sandwiched between the recliner assembly and the seat frame that can cause the joint to relax or by inadequate bolt torque during manufacture of the seat. Additionally, on some seats having the EZ Entry feature, even without foam and/or fabric sandwiched in the joint, bolts torqued to proper specification can loosen from normal service loads created during the actuation of the EZ Entry feature.

To correct this condition, dealers will remove all foam and/or fabric sandwiched between the recliner assembly and the seat frame, install washers between the seat recliner and the seat frame at each attachment point, and install new attaching bolts torqued to a higher specification. These corrections will be performed on both the driver's and passenger's seat.

VEHICLES INVOLVED

Involved are CERTAIN 1993-94 C/K extended cab trucks equipped with front high-back bucket seats (A95) or 60/40 split bench seats (AE7) built within the following VIN breakpoints:

Plant Year Model Code From Through ---- ----- ---- ---- --------- 1993 C/K E SOP EOP 1993 C/K 1 SOP EOP 1994 C/K E SOP EOP 1994 C/K 1 SOP EOP

The specific vehicles involved in this campaign have been identified by Vehicle Identification Number (VIN) Computer Listings. These listings are furnished to all involved dealers with the campaign. Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) or SERVICENET prior to beginning campaign repairs.

DEALER CAMPAIGN RESPONSIBILITY

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

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.

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 owner 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.

If the name and address of the owner of an involved vehicle was unavailable to Pontiac-GMC Division at the time of campaign initiation, the dealer must 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 Pontiac-GMC Division (see copy of owner letter included with this bulletin) according to staggered mailing dates due to parts availability. 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

1. Inspect type of seat:

- If the vehicle has the production seat, proceed to step 2.

- If thevehicle has a non-production seat (i.e., conversion packages), proceed to step 16.

2. Remove entry lever handle from passenger seat.

3. Remove recliner lever handle.

4. Remove screws for side cover and remove plastic cover.

5. Peel velcro strip loose at bottom of seat back.

Note: For envelope trim seats on base level and leather interiors, remove retaining device, pull back cover and foam to allow access to upper bolts, and proceed to step 8.

6. Remove staple above zipper at lower center of seat back (if applicable).

7. Unzip seat back cover and pull back to allow access to upper bolts.

8. Remove and discard all four bolts attaching recliner mechanism.

Note: If one or more bolts break at or above the surface of the seat frame, they should be removed using appropriate care to ensure that the threads in the seat frame are not damaged. If a bolt breaks below the surface of the seat frame, or if inspection of the threads in the seat frame reveals damage, the seat frame should be replaced. Repairing of damaged threads should not be attempted.

9. Remove recliner mechanism and inspect for damage such as elongated holes or broken metal. Replace as necessary.

10. Inspect for trapped foam/material under the recliner mechanism in the lower bolt locations. While foam/material in the threads is irrelevant, there should be a 1. 5" diameter hole in the seat cushion material under the recliner mechanism to insure good metal-to-metal contact (Figure 1).

11. If foam/material is present under the recliner mechanism to frame mating surface, remove material with a putty knife to provide metal-to-metal contact between the recliner mechanism washer and the seat frame.

12. If cloth material interferes with the mating surfaces, cut excess cloth away.

13. Install new bolts and washers using a beam-type wrench, e.g., dial (recommended), digital or pointer. Washer should be located directly against the seat frame. The easy entry cable (where applicable) should be located between the washers and the recliner mechanism. Assemble as follows:

1993 model trucks - (Figure 2)

On driver's and passenger's seats you are to use countersunk bolts with black anodized washers in the two upper bolt holes. IMPORTANT: Torque bolts to 42 Nm (31 ft. lb.).

14. Reinstall trim cover and levers.

15. Repeat above steps for the driver's seat.
