What kind of refrigerant for the AC does a 93 Ranger use?

A 1993 Ford Ranger likely used R-12 (Freon-12) refrigerant in its air conditioning system. However, R-12 is no longer manufactured or legally sold in many places due to its ozone-depleting properties. If your Ranger's AC needs refrigerant, you'll need to have it converted to an R-134a system, which requires some modifications and special oil changes. Do not attempt to recharge it with R-12 yourself.
