In 1993 GM still used R-12 refrigerant. If you look on the left side of the engine bay and to the back at the firewall there is the A/C unit and it should have a yellow label on top that tells you what type and how much, usually about 2.25 lbs. Also look around the left shock tower and radiator support for an additional label that may tell you if it has been converted over to the R-134a refrigerant.
