OK, some may have read my post about my a/c compressor running constantly on my 95 Concorde. Fast forward to today. Since I've owned this car, (probably 2.5 years) I've replaced the a/c compressor, this will be the 3rd. one. First one lasted till 2011, then replaced it with a known good in, it lasted probably 3/4 year, then it locked up, replaced it with another used one, it lasted 2 seasons. Now, let it go till this past weekend, bought a rebuilt one, replaced it and now it's locked up after about 24 hours !!! Rec/dryers were replaced each time. Is there a way to flush out the system to correct this or should I just give up. I realize buying used compressors is not the wisest thing, but am I having a tough time picking used ones or is there something the system that's causing this perhaps? I don't mind fixing something, but numerous times?!

Yes they make cans of AC flush and you should be using them. Gotta get the metal form the failed compressors outta the system for a new comp to last.

Bill there is a block by the firewall.It acts like an orifice tube.I cant remember if they used an orifice tube that year or not.We always replaced the orifice as it has a fine screen to filter.Lots of places dont flush the system if the compressor didnt come apart inside.Most failures I did were bad clutches.Usually they cost as much as a reman compressor.Some you have to buy a complete compressor.They have flush kits at parts store.But you probally should clean the block on the firewall.They also can be replaced.Lines come off and it bolts to the evap connection.Its been a while since I tore one apart.Oh by the way reman compressors are usually a good buy.We used mostly 4 seasons.Rocky

Ron I though they still had the Expansion valve.Like I said nothing wrong with a reman compressor as long as its a quality one.Ive replaced a few hundred and only had 1 bad one and it just leaked.Warranty covered it.Rocky

Don't use the same AC mechanic Already have someone else lined up
Add an extra filter in front of the compressor. Where are those available?
Never use used AC parts on something you plan on keeping

Bill we used to get filters from NAPA.I believe ant good parts store carries them.Make sure the lines get flushed also.Rocky

The quick charge kits with the gauge are decent.If its low they usually drop the temp some.I found best to have the system evacuated and vacuum drawn.Then recharge with the proper charge.Rocky

The kits usually work decent if its just low.They all lose freon thru time and hoses,etc.Check the rad and condensor dosent have crap stuck to it.I usually turn on high and flush with cold water.You should feel the temp drop.Ive also seen a lot of older cars with contaminated freon.We always used a tester at work before we even touched a system.I had one the identifier said had benezyne etc in it.When you evac the stuff in the system goes into your tank and you dont want to contaminate a tank of clean stuff.We always used the stuff with dye in it.If there was or it develops a leak its easy to spot.Rocky
