CAMPAIGN: INCORRECT 'MEM-CAL' CAUSES EVENTUAL A/C FAILURE
SUBJECT: Calibrator, PROM ("Mem-cal")
MODELS/YEARS: Certain 1989 Cutlass Calais With 3300 V-6 Engine (VIN Code "N") And C60 Air Conditioning
CONDITION
Some 1989 Oldsmobile Cutlass Calais model vehicles with the 3300 V6 (RPO LG7) engine and Air Conditioning (RPO C60) were built with a "Mem-cal" in the Engine Control Module which allows the Air Conditioning Compressor to operate at low system pressures during low ambient temperatures or when there is a loss of Freon. This operation will eventually cause the compressor to fail due to the lack of proper internal lubrication.
VEHICLES INVOLVED
Involved are certain 1989 Oldsmobile Cutlass Calais model vehicles with the 3300 V6 (RPO LG7, VIN Code "N") engine and Air Conditioning (RPO C60) within the following VIN breakpoints:
From Through and including
Start of Production KM232372
NOTICE: Two "Mem-cal" part numbers are used in the campaign correction, one for Federal Emissions (RPO NA5, P/N 16136602) and one for California Emissions (RPO NB2, P/N 16136607).
The VIN sequence listing provided to each dealer indicates in the page headings which emissions system (NA5 or NB2) is on the vehicles listed on the page. The Vehicle Emission Control Information Label on the radiator upper mounting support and/or the "Service Parts Identification" label on the trunk lid also identify the emissions system on the vehicle.
DO NOT ASSUME THAT ALL VEHICLES OUTSIDE THE STATE OF CALIFORNIA ARE NECESSARILY EQUIPPED WITH FEDERAL (NA5) EMISSIONS SYSTEMS.
DEALER ACTION
To prevent this condition from occurring, dealers are to replace the Mem-cal in the Engine Control Module (ECM), using the appropriate part number according to which emissions system is on the vehicle.
Dealers are to perform this campaign on all vehicles involved at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your new vehicle inventory and arrange for the campaign correction to be performed.
SERVICE PROCEDURE
1. From one of the following sources, determine which Mem-cal is required for the vehicle to be serviced:
A. Dealer VIN Sequence list for Product Campaign 89-C-02.
B. The Service Parts identification label on the trunk lid.
C. The Vehicle Emission Control information Label on the radiator upper mounting support.
For Federal Emissions (RPO NA5), use Mem-cal P/N 16136602. For California Emissions (RPO NB2), use Mem-cal P/N 16136607.
NOTICE: Do not assume the Mem-cal Part Number usage by geographical location of your dealership; confirm the actual part number Mem-cal required.
2. Replace the Mem-cal using the Service Procedure shown at Page 3300 (VIN N) 6E3-Cl-5 in the 1989 Oldsmobile Cutlass Calais Service Manual.
3. Install Campaign Identification Label.
CAMPAIGN IDENTIFICATION LABEL
Each label provides space to print the campaign number, and the five (5) digit dealer code of the dealer performing the campaign. Insert this information with a typewriter or ballpoint pen. When installing label, clean and dry the surface of the radiator support tie bar and apply the campaign label where it is readily visible.
PARTS INFORMATION
Mem-cals will be shipped to Dealers with involved vehicles on a "No Charge' basis starting on or about November 23, 1988. It is anticipated Mem-cals will all be shipped by Christmas. Cooler climates are targeted for parts shipment before warmer regions. Parts will not be billed on dealers' parts account.
Dealers should not order parts from GMSPO until March 1, 1989. If transfers make additional parts necessary, contact Lansing Lithographers at (517) 482-0697 up to February 28, 1989. VIN information will be required when ordering parts from Lansing Lithographers.

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.
