GM Full-Size Trucks 1980-1987 Repair Guide

Air Conditioning Components



Repair or service of air conditioning components is not covered by this guide, because of the risk of personal injury or death, and because of the legal ramifications of servicing these components without the proper EPA certification and experience. Cost, personal injury or death, environmental damage, and legal considerations (such as the fact that it is a federal crime to vent refrigerant into the atmosphere), dictate that the A/C components on your vehicle should be serviced only by a Motor Vehicle Air Conditioning (MVAC) trained, and EPA certified automotive technician.

If your vehicle's A/C system uses R-12 refrigerant and is in need of recharging, the A/C system can be converted over to R-134a refrigerant (less environmentally harmful and expensive). Refer to Routine Maintenance for additional information on R-12 to R-134a conversions, and for additional considerations dealing with your vehicle's A/C system.
