Centrifugal Compressor and Rotary Compressor is preferred with refrigerant R-113.
The Reciprocating compressors is the type of compressor that is preferred with refrigerant R-113.

Your condensor outside , where the compressor is . should have an information plate showing the type of refrigerant used
If you have a scroll type compressor, at shutdown the compressor stops pumping and the hi & lo refrigerant pressures equalize, breifly spinning the compressor backwards until they are fully equal. This is normal for these type compressors.
Look for a label on the underside of the hood, around the radiator crossover, or the compressor. The label will tell you the type and quantity of refrigerant, and also the type of refrigerant oil used in the system.
Generally, because something is wrong with it. Maybe a bearing went out, maybe the compressor is just worn, maybe it was damaged because of a refrigerant overcharge, compressor oil overcharge, or the wrong type of compressor oil used. Could be a number of reasons.
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
Look on the outdoor compressor, there should be a sticker that tells you what kind of refrigerant it uses. If it says r22, it is the old type.
Your 1990 has R12 refrigerant in it which isn't available anymore at parts stores. To add refrigerant to your vehicle you will have to get the a/c system vaccuumed and retrofitted to accept new r134a refrigerant and pag100 compressor oil. You can take it to a shop to get it vaccuumed and retrofit it yourself with kits from your local Autozone. -broncomudder89
Evacuate A/C system and properly dispose of old refrigerant. Replace part. Perform a complete A/C system service (SAFELY & PROPERLY). (Personell certified to handle refrigerant may need to install correct type and amount of compressor oil and refrigerant)
Refrigerant... it's only Freon if it was manufactured by Dupont and marketed under that name... and a 2000 model year vehicle will use R134a refrigerant and PAG compressor oil.
You would have to replace the orifice tube, accumulator or receiver-drier (which one you have depends on what type of AC system you have), as well as remove all of the R12 refrigerant, and you'd have to replace the compressor oil with PAG.
