FLOOR PAN DRAIN PLUG DISLODGED INSPECT/REINSTALL DRAIN PLUG

Subject: PRODUCT CAMPAIGN 91C12 FLOOR PAN DRAIN PLUGS

Model and Year: 1991 GEO METRO 5-DOOR HATCHBACK

General Motors has determined that certain 1991 Geo Metro 5-Door Hatchback model vehicles may have been assembled with the floor pan drain plugs dislodged from their positions. This may result in water entering the vehicle interior through the resulting openings in the floor pan.

To correct this condition, dealers are to inspect the vehicle floor pan of each involved vehicle and reinstall drain plug(s) as required.

VEHICLES INVOLVED

Involved are certain 1991 Geo Metro model vehicles built within the following VIN breakpoints:

PLANT YEAR MODEL PLANT CODE FROM THROUGH ---- ------------ ----------- ----- -------- -------- 1991 M-Car Ingersoll "6" M6725217 M6738108 (5-Door Hatchback)

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 involved dealers with the campaign bulletin. Owner name and address data furnished 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 this 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 Chevrolet Motor Division (see copy of owner letter included with this bulletin).

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.
