I have moved you question to start a new thread of your own. We don't address multiple vehicles within the same thread.


As we consistently tell people that when a compressor fails it tears up inside and all the debris spreads through the system, especially the condenser. Some condensers are designed so they can be flushed and some cannot be flushed. If you simply replace the compressor, you not only haven't found the cause of the original failure but you now have a plugged up system so the life expectancy of your new compressor is basically nothing. If you chose a reman instead of new compressor, your chance are even worse.
It takes a special chemical and a lot of air pressure to flush the system and if it's equipped with a bypass type condenser it cannot be flushed and will have to be replaced.

How did you determine you needed a compressor?

BTW - you tagged onto about year old thread so it's moved and on it's own now,

Hey Tom
We must have been moving it at the same time because I detached it from that old thread and then went back and found a "moved question" link like it was a new question when I moved it.

Yup - working at the same time. We need to know more about this vehicle. If a second compressor in its life there will be more work. When it's just a leak and caught for the "Black Death" as it's called you can't cut corners and get away with it for a while but problems will return sooner unless you do it right.

The most common failure IMO for a compressor is lack of lubrication and a leaking system can't carry enough oil so they burn up.

Not so much where I live but warmer climates the dang things are working hard and doesn't take long to burn one out.

Jeeps and many Chrysler products are well known for the dreaded evaporator leaking! Big job to swap most of those which is why I asked why you thought it needed a compressor. Fast leaks can shut system down quickly with less or perhaps no damage to the compressor,
