CAMPAIGN:LAMP CONTROL MODULE

SUBJECT: LAMP CONTROL MODULE

YEAR: 1995

MODEL: NINETY EIGHT W/TWILIGHT SENTINEL (RPO T82)

TO: ALL OLDSMOBILE RETAILERS

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle 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 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 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 included copy of the letter that is being sent to owners, the owners are being instructed to contact OCAN (Oldsmobile Customer Assistance Network) if their retailer 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 determined that a defect which relates to motor vehicle safety exists in certain 1995 Oldsmobile Ninety Eight model vehicles equipped with twilight sentinel. Some of these vehicles were assembled with Lighting Control Modules which may experience excessive current leakage due to damaged surface mounting capacitors. This condition could result in a loss of head lamps and park lamps. Sudden los of head lamp lighting could reduce driver visibility, which could result in a vehicle crash without prior warning.

In addition, the potential also exists that the head lamps can not be turned off or that they could turn on while the vehicle is parked. Both of these conditions would result in loss of battery state of charge and the inability to restart the vehicle.

To prevent the possibility of these conditions from occurring, retailers are to replace the lamp control module on involved vehicles.

VEHICLES INVOLVED

Certain 1995 Oldsmobile Ninety Eight vehicles equipped with twilight sentinel (RPO T82) within the breakpoints listed below:

PLANT THROUGH & YEAR MODEL MODEL NAME CODE VIN BEGINNING INCLUDING ----------------------------------------------------------------------------- 1995 C Ninety Eight 4 S4300018 S4300972

+ Not all vehicles within the above VIN breakpoints are involved.

NOTICE: Only certain vehicles within these VIN breakpoints are affected. Please check your retailer VIN listings or VISS (Vehicle Information Service System) for campaign involvement of suspect vehicles. Involved vehicles have been identified by Vehicle Identification Number listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved retailers with the campaign bulletin. Owner name and address data furnished will enable retailers 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 retailer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

All vehicles listed on the retailer's printout will require correction. Other suspect vehicles should be checked for campaign involvement by utilizing VISS (Vehicle Information Service System).

PARTS INFORMATION

A pre-shipment of parts will be sent to involved retailers on October 13, 1994. Pre-shipment parts will equal parts for 100% of the number of vehicles to be repaired. Pre-shipment parts will be charged to the retailer's open parts account. Parts received for recently transferred vehicles should be forwarded by the original retailer to the retailer that received the transferred vehicle

If additional parts are required to complete this campaign, they are to be obtained from GMSPO (General Motors Service Parts Operations). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a C.I.O. order, with NO special instruction code, but order on an advise code (2).

OWNER LETTER

Dear 1995 Oldsmobile Ninety Eight Owner:

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

REASON FOR THIS SAFETY RECALL: General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1995 Oldsmobile Ninety Eight model vehicles equipped with twilight sentinel. Some of these vehicles were assembled with Lighting Control Modules which may experience excessive current leakage due to damaged surface mounting capacitors. This condition could result in a loss of head lamps and park lamps. Sudden loss of head lamp lighting could reduce driver visibility, which could result in a vehicle crash without prior warning.

In addition, the potential also exists that the head lamps can not be turned off or that they could turn on while the vehicle is parked. Both of these conditions would result in loss of battery state of charge and the inability to restart the vehicle.

IMPORTANT: Some Oldsmobile Ninety Eight owners are also involved in a campaign that requires replacement of the head lamp switch. If you have received a prior letter for the head lamp switch campaign (campaign number 95-C-01 or 95-C-01 A), please be aware that this is an additional campaign and both campaigns will need to be completed on your vehicle.

WHAT WE WILL DO: To prevent the possibility of these conditions from occurring, retailers are to replace the lamp control module on involved vehicles. This service will be performed for you at no charge.

WHAT YOU SHOULD DO: Please contact your Oldsmobile retailer immediately to arrange a service date. Instructions have been sent to your retailer. It is estimated that parts will be available to your retailer October 13, 1994. Please ask your retailer if you wish an estimate of the total time needed to schedule, process and return your vehicle. Included in this time would be about eighteen (18) minutes for a technician to perform the work required.

You may have your vehicle serviced at the authorized Oldsmobile retailer of your choice.

Your Oldsmobile retailer is best equipped to obtain parts and provide service to promptly correct your vehicle. However, if you take your vehicle to your retailer on the agreed service date, and they do not remedy this condition then or within five days, we suggest you call Oldsmobile Customer Assistance (1-800-442-6537).

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.
