For 1990-2009 cars

# CAMPAIGN: SEAT BELT BUCKLES MAY NOT LATCH OR RELEASE

#### Models: 1984-90 Chevrolet Camaro and Pontiac Firebird

TO. ALL GENERAL MOTORS DEALERS

# THIS BULLETIN CANCELS AND SUPERSEDES CAMPAIGN BULLETIN 0A15 ISSUED JULY, 1990. THE DEFECT INVOLVED, PARTS INFORMATION, SERVICE PROCEDURE AND CLAIM INFORMATION SECTIONS HAVE BEEN REVISED. ADDITIONALLY, A SPECIAL TOOLS SECTION HAS BEEN ADDED. ALL COPIES OF THE ORIGINAL BULLETIN SHOULD BE DESTROYED. REVISED INFORMATION IS SHOWN IN BOLD TYPE AND DENOTED BY A # SIGN.

#### DEFECT INVOLVED:

General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in some 1984-90 Chevrolet Camaro and Pontiac Firebird model vehicles. Some seat belt buckle assemblies in affected vehicles may not latch, or may not release, due to fracture of the red push button which can occur during seat belt connection or disconnection. These buckle malfunctions would prevent a person from using their seat belt system and the risk of injury to an unbelted person in an accident would be increased.

# To correct this condition, all involved vehicles will have the pushbutton assemblies replaced and have a protector shield added (except for certain 1989 and all 1990 vehicles which have revised lower cover ramps and as a result do not need protectors). Also, any buckle assemblies which are found not to function correctly, or which have fractured pushbuttons, will be replaced.

#### VEHICLES INVOLVED:

Involved are 1984-90 Chevrolet Camaro and Pontiac Firebird model vehicles built within the following VIN breakpoints:

CHEVROLET AND PONTIAC

YEAR MODEL PLANT FROM THROUGH

1984 F Van Nuys (L) SOP EOP 1984 F Norwood (N) SOP EOP 1985 F Van Nuys (L) SOP EOP 1985 F Norwood (N) SOP EOP 1986 F Van Nuys (L) SOP EOP 1986 F Norwood (N) SOP EOP 1987 F Van Nuys (L) SOP EOP 1987 F Norwood (N) SOP EOP 1988 F Van Nuys (L) SOP EOP 1989 F Van Nuys (L) SOP EOP 1990 F Van Nuys (L) SOP EOP

Review the owner's documentation, and process under Repair Code T1605 (authorization is required).

# SERVICE PROCEDURE: ----------------------- This procedure must be performed on all 4 buckle assemblies to complete the campaign.

1. Inspect all 4 buckle assemblies for the following:

* Improper Function - Fasten seat belt by inserting latchplate into buckle. Pull on belt webbing to insure proper latching. Release latch. Repeat five times for each buckle to insure proper operation.

* Missing Or Fractured Red Pushbutton - Figure #1 below illustrates a typical fracture.

If the buckle does not function correctly, or if the red pushbutton is broken, replacement of that buckle is required - see Body Service Manual for procedure (seat belt section).

NOTE THAT ON 1984 VEHICLES WITH BROWN OR CHARCOAL BUCKLE ASSEMBLIES, IF A PUSHBUTTON DOES NOT FUNCTION PROPERLY, OR IT IS BROKEN, ALL OF THE BUCKLE ASSEMBLIES MUST BE REPLACED WITH BLACK BUCKLE ASSEMBLIES DUE TO COLOUR AVAILABILITY.

If the pushbutton is not broken, and the buckle functions properly, continue on to step 2. BE CERTAIN TO CHECK ALL BUCKLES.

2. Remove pushbutton by inserting pushbutton removal tool (J-38886-1) under the edge of the pushbutton in a horizontal position and then rotate tool to a vertical position. See Figure #3.

#### NOTICE: Screw tip must be backed out towards top of tool to allow proper clearance for tool insertion.

Finger tighten screw until the screw head has bottomed out on the tool. Be certain to keep tool as vertical as possible.

#### NOTICE: Pushbutton may fracture at this time - this is acceptable.

Gently rock the tool in a side-to-side motion as shown in Figure #3 on the next page to dislodge the pushbutton cap. DO NOT PRY TOOL ON EDGE OF BUCKLE.

3. Inspect the just removed pushbutton for any fractures. Figure #2 below illustrates a typical pushbutton fracture.

* If pushbutton is not fractured, continue to step 4.

* If pushbutton is fractured, locate the fractured piece and insure that it is not in the buckle mechanism as it may interfere with buckle operation when reassembled. Continue on to step 4 when this is completed.

4. Discard removed pushbutton (and any fractured pieces).

5. Inspect pushbutton spring inside buckle to determine if it is still secured under the pushbutton retainer (black). See Figure #4.

* If pushbutton spring is secure, continue to step 6.

***************************************************************************** REFER TO FIGURE #3: 1. Insert tool. 2. Insure tool is vertical. 3. Finger tighten until screw has bottomed on tool. 4. Rock tool side to side (See Illustration).

Pushbutton Removal (figure #3)

After screw has been fully tightened, rock tool side to side and remove pushbutton. *****************************************************************************

* If the spring is not secure, reposition the original spring (or install replacement spring if the original was lost or damaged in the removal of the pushbutton cap) using the spring installation tool (J-38886-2).

Install the pushbutton spring on the spring installation tool as illustrated below in Figure #5.

#### NOTICE: The opposite end of the spring installation tool may be used as a hook, if necessary, to aid in positioning the pushbutton retainer (black) - see Figure #6 below.

Install the pushbutton spring on the detent lever. Note that there are two different detent lever designs using either one or two retaining nubs - Figure #7. The pushbutton spring must be positioned over the retaining nub(s) on the detent lever and secured under the pushbutton - Figure #8.

***************************************************************************** FIGURE #7 Different Detent Levers --------- Position spring under pushbutton retainer

FIGURE #8 Pushbutton Spring Installation ---------- - Locate pushbutton spring to detent lever over retaining nubs

- Release spring from tool by squeezing the sides of the tool. Use finger of tool to maintain position of spring under retainer while extracting tool. *****************************************************************************

6. Install a new pushbutton from the service kit by inserting spring installation tool between buckle cover and pushbutton retainer to move the button away from the cover - see Figure #9. Locate new red pushbutton to the pushbutton retainer and push into position until an audible 'CLICK' is heard. Remove the tool from the buckle assembly.

#### NOTICE: Pushbutton should now move up and down freely. If it does not, repeat steps 2-6 to remove and reinstall pushbutton.

7. Buckle protector installation.

#### NOTICE: Buckles in some 1989 vehicles and buckles in all 1990 model year vehicles will not require the installation of buckle protectors. To determine if protectors are needed on 1989 vehicle buckles, note the assembly date stamp on the lower cover - Figure #10 on next page. If the stamp on the buckle is after 120489 (April 12, 1989), it will not require a protector. These buckles have revised lower cover ramps and do not need an additional protector.

After determining if a vehicle requires protectors, position stainless steel protector onto buckle lower cover - Figure #11. Push steel protector onto cover until it snaps securely.

8. Perform final inspection of safety belt by inserting the latchplate into the buckle and pulling on the safety belt webbing to insure proper latching. Unlatch and repeat this step five times to assure proper operation.

9. Install Campaign Identification Label.

#### INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL

Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.

Dear General Motors Customer:

As we informed you in our previous letter, General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in certain 1984-90 Chevrolet Camaro and Pontiac Firebird model vehicles. Some seat belt buckle assemblies in these vehicles may not latch, or may not release, due to fracture of the red pushbutton which can occur during seat belt connection or disconnection. These buckle malfunctions would prevent a person from using his seat belt system, and the risk of injury to an unbelted person in an accident would be increased.

In our previous letter, we made replacement of all vehicle seat belt buckle assemblies available to those owners who were currently experiencing any of the above conditions. However, since our last contact, General Motors has developed a preventative repair for those vehicles which have not experienced a pushbutton fracture or have not had all seat belt buckles replaced. If you had your seat belt buckle replaced following receipt of our previous letter this current letter does not apply to you.

To prevent the possibility of a pushbutton fracture condition occurring, your GM dealer will replace all pushbutton assemblies and install protector shields to the buckle assemblies (except for certain 1989 and all 1990 vehicles which do not need protectors). Also, any buckle assemblies which are found to have fractured buttons will be replaced.

This service will be performed for you at no charge.

Please contact your GM dealer as soon as possible to arrange a service date so that the dealer may order the proper parts to perform this repair. You may also make arrangements to have the vehicle towed to the dealer if the driver-side buckle is inoperative.

This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.

Further assistance, if required, may be obtained from our Customer Assistance Centre, toll free, by calling 1-800-263-3777, or if you live in Quebec, 1-800-263-7854.

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.
