Very Likely, Run By Any Parts House, Let Them Look To Be Assured. It May Have Been Converted To R134A, They Also Can Tell You By The Fittings. From Factory It Was R12. GOOD LUCK

R12
Freon is R12. Your 1997 Chevy uses R134 Refrigerant.
I would be surprised if it was anything but R12
R-134 should be the refrigerant as R12 was banned in 1996.
A 1993 Toyota 4Runner uses R12 refrigerant. The 1993 Toyota 4Runner requires 30 ounces of R12 for all engine types.
OEM refrigerant which came installed in 1993 was Freon R12. I suggest you convert it to R134a if it has not already been converted. R12 is far to expensive.
There is no need to ever change the refrigerant which is R134 and not Freon R12.
It came with R12 Freon. As R12 is cost prohibitive, have the unit converted to R134a refrigerant or a similar substitute.
A 1987 Chevy Blazer uses R12 refrigerant as shipped from the factory. Most have been converted to the more environmentally friendly R134a.
There should be a fitting with a screw top on it somewhere in the AC hose in the engine compartment. Use R134A, not R12
