-------------------------
General Motors has determined that certain 1993-95 Chevrolet Geo Prizm model vehicles may have been assembled in such a way as to allow any liquid spilled in the rear center console to leak through to the Supplemental Inflatable Restraint System (SIR) center sensor. Any liquid spilled in this area may leak onto the circuit board and damage the sensor. This could cause the airbag warning light to illuminate and stay "ON" during normal driving conditions. There is also a remote possibility that this condition could cause the airbag to inadvertently deploy.
To prevent the possibility of these conditions occurring, dealers are to inspect for evidence of liquids spilled into/onto the center sensor and connector. Center sensors found to have experienced a previous liquid spill will be replaced and the connector cleaned. Vehicles that have not experienced liquid intrusion will have a vinyl sheet affixed to the top of the center sensor. This sheet will deflect any future liquid spills that may leak through the rear center console and onto the center sensor.
Involved are certain 1993-95 Chevrolet Geo Prizm model vehicles (Excluding LSi Model), built within the following VIN breakpoints:
PLANT YEAR MODEL PLANT CODE FROM THROUGH ---- ---- ----- ---- ---- -------
1993 Prizm Fremont "Z" PZ000003 PZ075500 1994 Prizm Fremont "Z" RZ000001 RZ108000 1995 Prizm Fremont "Z" SZ000001 SZ050051
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.
A pre-shipment of part number (vinyl sheet) 94856382 will be sent to involved dealers the week of May 1, 1996. Preshipment will equal parts for 50% of the number of vehicles to be repaired. Pre-shipment parts will be charged to the dealers, open parts account.
Additional parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO) . Normal orders should be placed on a DRO = Daily Replenishment Order. An emergency requirement should be ordered on a CSO Customer Special Order.

Dear Chevrolet Geo Prizm Owner:
This notice is sent to inform you that Chevrolet Motor Division is conducting a recall campaign that includes your vehicle.
REASON FOR THIS RECALL
General Motors has determined that certain 1993-95 Chevrolet Geo Prizm model vehicles may have been assembled in such a way as to allow liquid spilled in the rear console box to leak through to the Supplemental Inflatable Restraint. System (SIR) center sensor and damage the circuit board. Any liquid spilled in this area may leak onto the circuit board. This could cause the airbag warning light to illuminate and stay "ON" during normal driving conditions. There is also a remote possibility that this condition could cause the airbag to inadvertently deploy.
WHAT WE WILL DO
To prevent the possibility of these conditions occurring, your dealer will inspect for evidence of liquids spilled into/onto the center sensor and connector. Center sensors found to have experienced a previous liquid spill will be replaced and the connector cleaned. Vehicles that have not experienced liquid intrusion will have a vinyl sheet affixed to the top of the center sensor. This sheet will deflect any future liquid spills that may leak through the rear console box.
WHAT YOU SHOULD DO
Please contact your Chevrolet Geo dealer as soon as possible to arrange a service date and so the dealer may order the necessary parts for the repair.
Instructions for making this correction have been sent to your dealer and parts are available. You may ask your dealer if you wish to know how much time will be needed to schedule and process your vehicle.
To avoid future problems, please do not set liquid/drink containers in the rear console box. Liquids spilled in this area may damage the function of the air bag. Please use the cup holder located near the radio for your beverage.
The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.

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.
