What kind of freon is used in a 1993 Chevrolet air conditioner?
1993 Chevrolet vehicles most likely used R-12 (Freon-12) refrigerant in their air conditioning systems. However, it's crucial to verify this by checking the sticker on the AC system itself. R-12 is no longer produced due to its ozone-depleting properties, and any service would require a replacement refrigerant (like R-134a) and possibly system modifications.
