Hi All:
Anybody ever have issues with going through a/c compressors? I am on my 3rd in less than 2 years, they keep frying the clutches. Someone mentioned a stuck relay or a condenser fan problem. Any input is greatly appreciated

Are you replacing the entire compressor or just the clutches? Where they aftermarket or OEM?

If you over charge the ac or it wont cycle the compressor will build up to much head pressur and the clutch will slip till its burnt up .. also if you have an engine oil leak oil will get on the clutch and cause it to slip also..Wipe your hand around the clutch (with the engine off and cold) and see if there is any oil on the clutch..

If you're buying aftermarket or rebuilt compressors, then this is perfectly normal?

What does the OT look like post repair? And what are your high and low pressures post repair? Are the fans running? Temperature drop across the condenser?

Another thing to consider Scott is if the original compressor had a catastrophic failure. In other words, if it "blew" there could be debris remaining in the lines that compromised all succeeding compressors. I agree with Ranger in that you should go OEM on a replacement unit. Check your orifice screen for debris, and if you see any junk in there, have the lines flushed before putting on another compressor.

If Gregs scenario is correct, you'll need to do more than just flush the lines. You'll have to replace the condenser and accumulator.
