CAMPAIGN: PUSH-PULL HEADLIGHT SWITCH-LOSS OF HEADLIGHTS. Cadillac Cimarron 1986

SUBJECT: 1986 DE VILLE, FLEETWOOD (FWD) AND CIMARRON PUSH-PULL HEADLIGHT SWITCH REPLACEMENT POTENTIAL LOSS OF HEADLIGHTS

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a product campaign of this type, must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequatefy 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 allow- ance 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 owner letter, the owners are being instructed to contact the nearest Cadillac Zone Office if their dealer does not remedy the condition within five days of the agreed service date. If the condition is not remedied within a reasonable time, the owners are instructed how to contact the National Highway Traffic Safety Administration.

CONDITION

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1986 De Villes, Fleetwoods and Cimarrons. The push-pull headlight switch might have been manufactured with electrical contacts which could potentially result in an intermittent headlight circuit. An intermittent circuit could cause the headlights to suddenly go out. Sudden loss of the headlights under severe weather or nighttime driving conditions could reduce driver visibility which might result in a vehicle crash without prior warning.

DEALER ACTION

To prevent this condition dealers are required to inspect, and if necessary, replace push-pull headlight switches on suspect vehicles per the Vehicles Involved and Service Procedure sections of this bulletin.

Dear Cadillac Owner:

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

Until you have had an opportunity to have your Cadillac corrected, you should be alert for signs of an intermittent headlight circuit. For example, there might be a temporary delay when you pull the headlight switch "ON," or the headlights might not light at all. If you experience these conditions, a gentle upward pressure on the headlight knob might light the headlights.

To prevent this condition from occurring, please contact your Cadillac dealer on or after the date shown below to arrange a service date to have your Cadillac inspected. Your dealer will check the headlight switch. If necessary, the switch will be replaced. This service will be completed at no charge to you.

Instructions have been sent to your Cadillac dealer. It is estimated that parts will be available May 8, 1986. The labor time necessary to perform this correction is approximately 35 minutes. Please allow your dealer additional time to process your vehicle.

Your Cadillac dealer is best equipped to obtain parts and provide service to ensure your Cadillac is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not remedy this condition on that date or within five days, we recommend you contact the nearest Cadillac Zone Office, either in person or by telephone. The Zone Office will assist you and the dealer in getting your vehicle corrected. The locations and telephone numbers of the Zone Offices are listed in your Warranty and Owner Assistance Information Booklet which is in your glove compartment.

After contacting your dealer and the Zone office, if you are still not satisfied 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, D.C. 20590, or call 800-424- 9393 (Washington, D.C. residents use 426-0123).
