In four months I replaced five air conditioner compressors. One new ACDelco brand and four used from damaged GMC cars. The new one took seven days working fine then the clutch burned out and compressor jammed. The used one all failed in the same way in two working days.
During this periods we change the air conditioner radiator cooler and filters with new parts and installed additional outside fan cooler. But still problem not solved.

Your assistance is highly appreciated.
Best regards

It was probably the compressor that blew up so if you do not flush the system from the evaporator back, and change orifice and receiver drier you will more than likely run into same problem. Once it is flushed (there is fluid available for that at auto parts) oil level has to be replaced and system has to be pumped down or evacuated with a vacuum pump for at least fifteen minutes then a Freon sweep has to be done then evacuated again. If that is not done your new parts will be damaged.

The system was flushed, evacuated two times and new filters and new orifice and dryer plus air conditioner radiator were installed after the first compressor replacement. That did not solve the problem.

Was oil checked in compressor after install? Was complete system flushed or just condenser and was orifice replaced after flushing. You did not know condition of used compressors and I would bet oil level was checked after flushing so they burned up.

The car was taken to expert shop specialized in air conditioner problems at the compressor first failure. They dismantled the system and flushed it. I brought new compressor, new condenser, new filter and dryer and oil can. They granted their work. But after seven days compressor jammed.

I returned the car. They disconnected all houses and flushed again and put used compressor. It works for two trips and compressor jammed. Car returned back then they ask to install outside fan cooler and I brought new one and they installed it and change the compressor. Two trips and failed. They ask me to get back the car to them in winter time.

I took the car to another shop working only in air conditioner. Old compressor installed. Air conditioner working fine only two trips. In morning compressor jammed up to now.

That is the whole story.

Your help is highly appreciated.

Without physically looking at this it is tough to tell whats going on but it sounds as if this has a serious problem of something not flushing out when it needs to. What you have said and what was actually done can be two different things, Not meaning on your part. I still believe there is trash in system and it is not getting out like it should.

Does the car have front and rear air? if so both front and rear need to be flushed, plus do you have a gauge set? I would pay close attention to the high side pressure, here is a link that can help.
