This will be listed somewhere on the unit or in the owner's manual. 1995 was the last year of production of R12 so your car may have R12 or R134. If it needs service, this is not a DIY job. You have neither the expertise not the tools to do this safely and correctly. Take it to a pro.
A 1999 Chevy Lumina 3.1 uses standard R-134a refrigerant. It has been used nearly exclusive in automobiles since R-12 was phased out in 1995.

R134a
