PRODUCT RECALL CAMPAIGN

PRODUCT SAFETY CAMPAIGN

#### SUBJECT: 98014 - WINDSHIELD WIPER LINK INTERFERENCE WITH TRACTION CONTROL SYSTEM (TCS) BRAKE LINE

#### MODELS: 1997-98 CHEVROLET VENTURE, PONTIAC TRANS SPORT AND OLDSMOBILE SILHOUETTE WITH TCS (RPO NW9)

THE HIGHWAY 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 CUSTOMER 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 CUSTOMER 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 REMEDIES, EVERY EFFORT MUST BE MADE TO PROMPTLY SCHEDULE AN APPOINTMENT WITH EACH CUSTOMER AND TO REPAIR THEIR VEHICLE AS SOON AS POSSIBLE. AS YOU WILL SEE IN READING THE ATTACHED COPY OF THE DIVISIONAL LETTER THAT IS BEING SENT TO CUSTOMERS, THE CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE APPROPRIATE CUSTOMER RELATIONS 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 DECIDED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN CERTAIN 1997-98 CHEVROLET VENTURE, PONTIAC TRANS SPORT AND OLDSMOBILE SILHOUETTE MODEL VEHICLES. WHEN THE WINDSHIELD WIPERS ON THESE VEHICLES ARE TURNED ON, THE WINDSHIELD WIPER LINKAGE ARM MAY CONTACT A BRAKE LINE CONNECTED TO THE TRACTION CONTROL SYSTEM (TCS) MODULATOR. THIS CONTACT COULD CAUSE THE WIPER LINKAGE ARM TO RUB THROUGH THE BRAKE LINE RESULTING IN A BRAKE FLUID LEAK, REDUCED BRAKE EFFECTIVENESS AND INCREASED STOPPING DISTANCES. PARTIAL LOSS OF BRAKING AT A TIME WHEN MINIMUM STOPPING DISTANCE IS REQUIRED COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.

TO CORRECT THIS CONDITION, DEALERS ARE TO INSTALL A BRAKE LINE CLIP WHICH ASSURES PROPER CLEARANCE. ADDITIONALLY, VEHICLES WILL BE INSPECTED FOR BRAKE LINE DAMAGE CAUSED BY THIS CONDITION AND ANY DAMAGED BRAKE LINES WILL BE REPLACED.

VEHICLES INVOLVED

INVOLVED ARE CERTAIN 1997-98 CHEVROLET VENTURE, PONTIAC TRANS SPORT AND OLDSMOBILE SILHOUETTE MODEL VEHICLES BUILT WITHIN THE FOLLOWING VIN BREAKPOINTS:

PRODUCT SAFETY CAMPAIGN

#### SUBJECT: CAMPAIGN 98014 - WINDSHIELD WIPER LINK INTERFERENCE WITH TRACTION CONTROL SYSTEM (TCS) BRAKE LINE

#### MODELS: 1997-98 CHEVROLET VENTURE, PONTIAC TRANS SPORT AND OLDSMOBILE SILHOUETTE WITH TCS (RPO NW9)

DEFECT INVOLVED

General Motors of Canada Limited has decided that a defect which relates to motor vehicle safety exists in certain 1997-98 Chevrolet Venture, Pontiac Trans Sport and Oldsmobile Silhouette model vehicles. When the windshield wipers on these vehicles are turned on, the windshield wiper linkage arm may contact a brake line connected to the traction control system (TCS) modulator. This contact could cause the wiper linkage arm to rub through the brake line resulting in a brake fluid leak, reduced brake effectiveness and increased stopping distances. Partial loss of braking at a time when minimum stopping distance is required could result in a vehicle crash without prior warning.

To correct this condition, dealers are to install a brake line clip which assures proper clearance. Additionally, vehicles will be inspected for brake line damage caused by this condition and any damaged brake lines will be replaced.

VEHICLES INVOLVED

Involved are certain 1997-98 Chevrolet Venture, Pontiac Trans Sport and Oldsmobile Silhouette model vehicles built within the following VIN breakpoints:

April 1998

Dear General Motors Customer:

General Motors of Canada Limited has decided that a defect which relates to motor vehicle safety exists in certain 1997-98 Chevrolet Venture, Pontiac Trans Sport and Oldsmobile Silhouette model vehicles. When the windshield wipers on these vehicles are turned on, the windshield wiper linkage arm may contact a brake line connected to the traction control system (TCS) modulator. This contact could cause the wiper linkage arm to rub through the brake line, resulting in a brake fluid leak, reduced brake effectiveness and increased stopping distances. Partial loss of braking at a time when minimum stopping distance is required could result in a vehicle crash without prior warning.

To correct this condition, your GM dealer will install a brake line clip which assures proper clearance. Additionally, your vehicle will be inspected for brake line damage caused by this condition and any damaged brake lines will be replaced.

This service will be provided for you at no charge.

Please contact your GM dealer as soon as possible to arrange a service date.

If parts are required, ask your dealer for details regarding their availability. If parts are not in stock, they can be ordered before scheduling your service date.

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.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
