Condition Involved, Dealer Action, Vehicles Involved & Owner Notification Infformation
CONDITION INVOLVEDGeneral Motors has determined that a defect which relates to motor vehicle safety exists in some 1987 Pontiac Bonnevilles when equipped with foglamps. The headlamp circuit breaker may overheat at low beam resulting in an intermittent headlamp circuit. An intermittent circuit could cause the headlamps and foglamps to suddenly go out. Sudden loss of the headlamps 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 from occurring, dealers are required to revise wiring for the forward lamp circuit on suspect vehicles, per the Vehicles Involved and Service Procedure section of this bulletin.
VEHICLES INVOLVED
Involved are certain 1987 Pontiac Bonneville models with foglamps, within the following VIN breakpoints:
Model
Year Plant Beginning Up To & Including
1987 Willow Run HW200003 HW240535
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 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 such 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).
