you can purchase retro kit at your local parts store. Be sure to follow the instructions. If you mix r134 with too much r12 oil it will copper coat the system and lock up the ac compressor.

Was built for R12, can be converted to R134a

I have personally seen and looked under the hood of a 1994 Chevrolet S10 Blazer (original 1st gen boxy body-style) that came from the factory with R12. It had been converted to R134a at some point, but it had all of the original labels under the hood that said "R12", "Charge R12", and R12 refrigerant under high pressure", etc. This particular 1994 S10 Blazer that I saw was manufactured in October 1993. Any S10 Blazer manufactured before October 1993 more than likely has R12. I also looked a 1994 Chevy K3500 with the turbo diesel engine that had R134a from the factory. This particular truck was manufactured in December 1993. This would indicate that GM started using R134a in its trucks in November or December 1993.

Freon is R12. Your 1997 Chevy uses R134 Refrigerant.

It came out with R12 and needs to be converted for R134. DON'T MIX THEM. My car with 134R cools as well as any car with R12. I switched my '92 Blazer S-10 over and have been very happy with it.

1995-1996 depending on the exact date of manufacture.
