anyone ever replace ac compressor on a cavalier?

Yes. The compressor, condenser, evaporator, orifice tube, and drier/accumulator.

ok cool, thanks for the help

sis had an 01 cavi and i never had to do the air on it

drain all the oil out of the compressor and measure it. replace the orifice tube if it has one. If you see any metal in the lines or orifice tube then you'll need to flush the lines with a suitable solvent, don't flush stuff into the accumulater, remove accumulater and seal the ends off before flushing. Replace all seals with new ones for safe measure. Try not to blow moist compresser air through the lines. Add the correct weight a/c oil back to the compresser, same amount as you removed. I like to add one additional ounce. After reassembly its pretty much just pull a vacuum for 30 minutes, seal it off and recheck the vacuum level after 15 minutes to verify you don't have a leak. Next you're ready for the refridgerant.

I know we have a couple a/c techs here online, just don't know if they're around today.

Red Heart Beat is dead on. However you could probably get away with just running the flush on the condensor as most metal collects there and at the orfice. If you have access to a lift it makes this repair much easier. I do alot of cavaliers at work and if its knocking its more than likely making glitter. Hahaha. Oh and after the repair check your cooling fans for proper operation, often times the heat/pressure is what kills the compressor. Sometimes they crap out on their own but I have seen cooling fans alot of times the root of the problem.

A 2002 is going to be 134a and NOT r-12. That changed around 1993-94 you can tell by the type of fitting for your a/c. If it has external threads it's r-12. Quick disconnect it's 134a. 134a runs at different pressure, is cheaper, you don't have to be certified to buy it from autozone.

You can do the whole thing in your garage if you have a vacuum pump, a/c flush solvent, A/C System Flush Kit and some gauges...you might even be able to fudge the gauges. But you MUST have a vacuum. Remove compressor, drier/accumulator, orifice tube(and then put the hose back together where the orifice tube WAS). Now you have two lengths and 4 outlets of pipe one goes through condenser and one goes through evap. Hook up the flush kit to air supply and get all the "glitter" out unless you enjoy changing compressors regularly. Point the hoses away form stuff you dont like covered in shiny liquid that smells like horse manure!!

All clean. New orifice tube, new drier/accumulator. Look on your old drier or somewheres else under your hood and look for how much refrigerant aka 134a and oil aka PAG-150 you need, in ounces. Pour like half in the compressor, and the rest in the line somewhere. Hook up the compressor and now you should have a closed system full of PAG oil, air, and moisture! (you can use oil to lube up seals if you needed new ones, but do NOT put the oil on the threads of ANYTHING) Without a vacuum now your a/c won't work for $hit. Pull a vacuum all night if you want, the longer the better. Then let it sit for 15 minutes and watch the gauge to see if you haev/can hear a leak(assuming you have a gauge) With a vacuum you can get a can or so of 134a right in the system without turning the compressor on. After that the compressor should suck down the rest of the 134a until you have replaced what the label said under the hood that you needed down the low side. Or alldata or Google will tell you how much oil and 134a to put in. Viola!! New a/c

Sure you can. It just isn't manufactured in the USA any more. Its really expensive and you cannot buy it legally unless you are certified by the EPA.
