CAMPAIGN: CRUISE CONTROL SERVO BUSHING. Pontiac Safari Wagon 1988

For 1990-2009 cars

# CAMPAIGN: CRUISE CONTROL SERVO BUSHING

#### MODELS AFFECTED 1984-88 Pontiac Vehicles With Cruise Control (RPO K34) On Certain Gasoline & Diesel Engines

#### TO: ALL PONTIAC 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 adequately repair within sixty 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 which is being sent to owners, the owners are being instructed to contact the Pontiac Customer Assistance Center 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, owners 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 some 1984 through 1988 Pontiac model vehicles equipped with cruise control on certain gasoline & diesel engines. A small nylon bushing in the cruise control servo bail (bracket) may slip out of place. This will not affect the operation of the cruise control, but it may cause intermittent increases in engine speed or dieseling (engine run-on with ignition off). If the vehicle is not serviced and the nylon bushing remains out of place, the servo rod assembly could wear through the bail. If the rod wears through the bail, it may catch on other engine components and possibly result in a stuck throttle. Although the vehicle can still be stopped with the service brake, an unexpected loss of accelerator control could result in a vehicle crash.

#### VEHICLES INVOLVED

Involved are certain 1984 through 1988 Pontiac vehicles equipped with Cruise Control (RPO K34) and 5.0L or 5.7L engines within the following VIN break- points:

Engine Beginning Up To Year Model Model Name VIN Codes VIN And Including ---- ----- ----------- ---------- --- -------------- 1984 G Grand Prix N EB200005 EB250584 N E2205277 E2306770 B Parisienne N EX202262 EX225153 N E9701426 E9743876 1985 B Parisienne N FX200001 FX268502 1986 B Parisienne Y GX201816 GX285088 1987 B Parisienne Y HA200001 HA207717 Y HX200001 HX211350 1988 B Parisienne Y JA200001 JA202809 Y JX200001 JX200001

Vehicles with Part Number 25074629 or Part Number 12335036 replacement Cruise Control Servos do not require the Bushing Kit called for in this Product Campaign Bulletin. Pontiac has eliminated a number of vehicles from this campaign which it was able to identify from warranty records as having the above replacement Servos installed. However, a large number of vehicles may have had the P/N 25074629 and P/N 12335036 Servos installed beyond warranty; those vehicles must be identified by inspection.

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 the 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

Owners will be notified of this campaign on their vehicles by Pontiac Division (see copy of Owner Letter included with this bulletin).

#### DEALER CAMPAIGN RESPONSIBILITY

To prevent this condition from occurring, dealers are to install a Bushing Kit on the Cruise Control Servo Bail. The cruise control servo assembly is not authorized as a replacement to correct for a missing or out of place bushing. Also, if other repairs are needed to the cruise control system, and the vehicle is out of warranty, the repair would be at the owner's expense.

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.

Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership or service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.

Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to have the required campaign correction performed.

#### PARTS INFORMATION

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operation (GMSPO). To ensure that these parts are obtained as soon as possible, they should be ordered on a C.I.O. order with no special instruction code, but on advise code (2). Quantity Description Part Number Per Vehicle ------------ ----------- ----------- Bushing Kit 25111444 1

#### SERVICE PROCEDURE

#### NOTICE: Figures 1 through 4 are for gasoline engines. Although the Servo Rod Assembly has a different shape and the Servo may be rotated on diesels, the service procedure remains the same.

1. Raise hood and install a fender cover on the left fender.

2. Examine the Cruise Control Servo. If the Bushing in the Bail of the Servo looks like it was formed in place (a permanent part of the Bail Assembly - see Figure 1), go directly to Step (12) and install a Campaign Identification Label.

If the Bushing is a "snap-in" bushing (with tabs) as shown in View "B" of Figure 2, continue to Step (3).

3. Disconnect any electrical and hose connections, if necessary, to the air leaner and remove air cleaner assembly.

4. Before removing the Spring Retainer from its adjustment hole in the Servo Rod Assembly, scribe a mark on the rod next to the hole to identify where the Spring Retainer is to be reinstalled (see Figure 2).

5. Remove the Spring Retainer. Do NOT remove the "Z" pin.

6. Align the "Z" pin with the rod as shown in View "A" of Figure 2. Then slide the rod rearward out of the bail (it may also be necessary to slightly collapse the Servo diaphragm and move the Bail forward).

Pinch the Bushing flange with a pair of pliers and remove the Bushing from the Bail. The Bushing may not be in the Bail hole as originally installed; it may be free to move on the Servo Rod Assembly. Remove and discard the old Bushing.

7. If the Servo Bail hole has a burr, file off the burr so that the Bail surface is flat on both sides.

8. Obtain Bushing Kit (P/N 25111444). Install the Bushing onto the Bail as shown in Figure 3, so that the two tabs snap firmly in place. If the bail is bent (or twisted) so that the new Bushing will not easily snap into place on the Bail (as shown in Figure 3), straighten the Bail as necessary.

9. Install the Clip over the Bushing and Bail as shown in Figures 3 & 4. Reinstall the Servo Rod Assembly through the new Bushing by positioning the "Z" pin as shown in View "A" of Figure 2. Reinstall the spring retainer in the original (marked) hole in the rod, pointing the spring retainer in the direction shown in Figure 4.

If the Servo Rod Assembly is missing the "Z" pin, install a second Spring Retainer in the end hole normally occupied by the "Z" pin.

10. Ensure that the throttle mechanism will return fully to the idle position.

11. Reinstall the air cleaner assembly and reconnect hose and electrical connections as may be appropriate.

12. Install a Campaign Identification Label, remove fender cover from left fender, and close hood.

#### CAMPAIGN IDENTIFICATION LABEL

Each vehicle modified in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label." Each label provides a space to include the campaign number, the five digit dealer code of the dealer performing the campaign service, and the date the vehicle was campaigned. This information may be inserted with a typewriter or ballpoint pen. Install the label only on a clean, dry surface of the radiator baffle where it is readily visible. (Additional campaign labels are available on stationery order as Form 7901-709).

Dear Pontiac Owner:

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

REASON FOR RECALL

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1984 through 1988 Pontiac model vehicles equipped with cruise control on certain gasoline & diesel engines. A small nylon bushing in the cruise control servo bail (bracket) may slip out of place. This will not affect the operation of the cruise control, but it may cause intermittent increases in engine speed or dieseling (engine run-on with ignition off). If the vehicle is not serviced and the nylon bushing remains out of place, the servo rod assembly could wear through the bail. If the rod wears through the bail, it may catch on other engine components and possibly result in a struck throttle. Although the vehicle can still be stopped with the service brake, an unexpected loss of accelerator control could result in a vehicle crash.

WHAT WE WILL DO

To prevent this condition from occurring on your vehicle, we will install a new bushing in your cruise control servo bail. Even if you or someone else has removed the old bushing, a new design bushing must be installed to prevent the rod in the throttle linkage from wearing through the cruise control servo bail. This service will be performed for you at no charge. The above repair is for bushing replacement only and does not cover other repairs to the cruise control system.

WHAT YOU SHOULD DO

Please contact your Pontiac dealer immediately to arrange a service date. Instructions have been sent to your dealer. It is estimated that parts will be available to your dealer July 20, 1989. The labor time to perform the work is about 15 minutes. Please allow additional time for your dealer to process your vehicle.

You may have your vehicle serviced at the authorized Pontiac dealer of your choice.

Your Pontiac dealer is best equipped to obtain parts and provide service to promptly correct your vehicle. However, if you take your vehicle to your dealer on the agreed service date, and they do not remedy this condition then or within five days, we suggest you contact the Pontiac Customer Assistance Center by calling: 1-800-762-2737.

If after contacting your dealer and the Pontiac Customer Assistance Center, 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, DC 20590 or call 1-800-424-9393 (Washington, DC residents use 366-0123

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.
