I changed the compressor in my 2004 2.7L. After vacuum testing the system and refilling it, it worked fine until the pressure increased and the clutch started smoking. The shop that refilled it didn’t notice until it was too late and the new clutch had burned up. So I put in another compressor. After filling this one, I watched it as we tested it. The new clutch began smoking as well. Am I looking at a blockage in the system or possibly a compressor relay?

What are the pressures doing? If the switch is bad it can do this.

Just climbing on the high side and remaining stable on the low, iirc. It’s been a while since I had the gauges on it. It blows cold and doesn’t leak.

Anytime you open the system you should also replace the dryer/accumulator.
Also, If the compressor self destructs (not that yours did) then the condenser should be replaced as well and the remaining system flushed to remove contaminants if you are looking for longevity

Sounds like you have a restriction for whatever reason it may be.

FWIW, here are a few scenarios when reading the gauges along with the symptoms/diagnosis for anyone interested:
