Well, air _conditioning_ compressor... (you do have an air compressor as well
You should find a sticker on the evaporator housing under the hood that identifies whether you've got R12 or R134a refrigerant in there. Since it'* a '95 I think you have R134a but find the sticker to be sure.
If the system is functioning right now but just a little weak, you can try topping off the R134a. Interdynamics sells a nice little conversion kit which is mainly aimed at people who want to convert from R12 to R134a, but which includes some useful pieces for a straight recharge as well, especially a filler hose with pressure gauge on it as well as three 15-oz. cans of refrigerant with oil.
The pressure gauge on the filler hose is very useful because overpressurizing (i.e. overfilling) the system can be as harmful as not having enough. Look in the usual department stores and you should find it; I think it was around $30 or so. I've seen it at Wal-Mart and at Meijer.
Note that they do sell what appears to be the same filling hose separately, without a gauge, but I wouldn't recommend trying to add R134a to a functioning system without that gauge to give you useful measurements, so you know when to stop.
