I am not sure if it is either freon or r-134a in 1995.

if it is freon, you need to convert it to r134a and then recharge it. (there are kits online)

if it is r134a, you can get one of those bottles of refridgerant at walmart or something and just recharge it yourself. make sure you get allthe necessary parts: bottle of r134, guage, hose.

they make some that has UV reactivity, so you can shine a black light in your engine bay to see if it is leaking somewhere.

if it took 10 years to leak out, it might not be worth the hassle.
