What freon does the 1992 Pontiac Bonneville use in its air conditioner?

The 1992 Pontiac Bonneville used R-12 (Freon-12) in its air conditioning system. However, it's important to note that R-12 is no longer manufactured due to its ozone-depleting properties. Any repairs would require a conversion to a modern, ozone-safe refrigerant like R-134a.
