CAMPAIGN:AIR CONDITIONING OVERCHARGE
Subject: PRODUCT CAMPAIGN 93C22 - AIR CONDITIONING SYSTEM OVERCHARGE
Model and Year: 1993 C/K SUBURBANS, BLAZERS AND CREW CABS WITH FRONT AIR CONDITIONING ONLY (RPO C60) AND BUILT AT JANESVILLE
To: All Chevrolet Dealers
General Motors has determined that certain 1993 Chevrolet C/K Suburban, Blazer and Crew Cab model vehicles with front air conditioning (RPO C60) and built at Janesville assembly plant may have their air conditioning (A/C) system overcharged. These vehicles received a 72 ounce charge of Freon instead of the specified 48 ounce charge. The 72 ounce charge is specified for vehicles with front and rear air conditioning. The air conditioning overcharge has several adverse effects on the air conditioning system performance including severe belt squeal during hot start, anticipated decreased durability of A/C components, compressor head pressures exceeding engineering objectives, and A/C outlet discharge temperature increased by 7 degrees Fahrenheit.
To prevent this condition from occurring, dealers are to evacuate the A/C system and recharge it with the correct amount of refrigerant.
VEHICLES INVOLVED
Involved are certain 1993 Chevrolet C/K Suburban, Blazer and Crew Cab model vehicles with front air conditioning (RPO C60) and built at Janesville assembly plant within the following VIN breakpoints:

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.

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.
