i am a/c certified and the way you would check is look on the compressor and it should say what refrigerant it uses and ui believe that at the year of 93 they started to change over to r-134a so check for your self and yes you can recharge it your self they do sell kits for it just be careful not to leak any into the air becauseit is a 10000 dollar fine and the person that turns you in gets a huge cash award also
