Dealer, Vehicle, Owner and Parts Information

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1986 Pontiac Bonneville, Grand Prix, Parisienne, Sunbird, T1000 and 6000 models. 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 flicker or 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 SERVICE PROCEDURE section of this bulletin.
