STSSCOTT Posted May 26, 2009 Report Share Posted May 26, 2009 Hi all: Anybody have issues that keep occurring like this....my a/c compressor has fried the clutch for the 3rd time in about 1 and a half years now. I tried a rebuilt the first time, new the second...I am installing everything right, replaced the dryer orifice tube, put a vacuum pump on the system for an hour before putting in the 134. There was a mention of the condenser fan, or a relay. I just don't know? Any help is appreciated Thanks in advance Scott Link to comment Share on other sites More sharing options...
Ranger Posted May 27, 2009 Report Share Posted May 27, 2009 Is it the clutch or the compressor that is going bad? Link to comment Share on other sites More sharing options...

KHE Posted May 27, 2009 Report Share Posted May 27, 2009 With the accessory belt off, turn the clutch by hand. You should feel some resistance but it shouldn't bind. Check the accessory belt for excessive wear on the ribs - if excessive wear is found, that may indicate binding in the compressor. Also check the wiring from the clutch - the wires could have worn through and causing the issue.

STSSCOTT Posted May 27, 2009 Author Report Share Posted May 27, 2009 the outermost ring on the clutch is completely broken off, and the wires are ok, it was like the compressor doesn't stop Link to comment Share on other sites More sharing options...
Texas Jim Posted May 27, 2009 Report Share Posted May 27, 2009 Just a thought... Could an incorrect AIRGAP on the clutch cause any of this? Link to comment Share on other sites More sharing options...

KHE Posted May 27, 2009 Report Share Posted May 27, 2009 Just a thought... Could an incorrect AIRGAP on the clutch cause any of this? Note likely but anything is possible. Usually, if the air gap is too wide, the clutch won't pull in all the time. If it is too narrow, the pulley will grind/squeal when the A/C is turned off. on 3 different compressors??? This reply contradicts the information you provided earlier. Are you replacing the clutch only or the whole compressor? If you could post a picture of the damaged pulley assembly, it would help in diagnosing the problem.

STSSCOTT Posted May 27, 2009 Author Report Share Posted May 27, 2009 I am replacing the whole compressor. the car just went to the body shop to repair a hit and run so I won't have it back til friday to be able to take pix Link to comment Share on other sites More sharing options...
rek Posted May 27, 2009 Report Share Posted May 27, 2009 A seized compressor will scrap the clutch...something has to give. If the first clutch blew up due to a seized compressor, chances are the system was full of crud. If you DIDN'T replace the condensor, after the first failure, the second and third compressor are eating dirt, caught in the unflushable condensor. My '96 clutch blew apart. The compressor was seized. There wasn't much crud on the orifice tube. rek Link to comment Share on other sites More sharing options...
Texas Jim Posted May 27, 2009 Report Share Posted May 27, 2009 OK........now I am completly confused. In the very first post, he says he is replacing the CLUTCH for the 3rd time in a year and a half. Then in a couple of post before this post, he says he is replacing the entire compressor. I am now wondering...the OTHER TWO TIMES...was the whole compressor replaced or was just the CLUTCH replaced.

I was suspecting debris in the condenser and accumulator, not to mention the lines. Link to comment Share on other sites More sharing options...

KHE Posted May 28, 2009 Report Share Posted May 28, 2009 Out of curiousity, when you replace the compressor, what brand are you using? Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...

STSSCOTT Posted May 29, 2009 Author Report Share Posted May 29, 2009 Out of curiousity, when you replace the compressor, what brand are you using? I'm not sure, not AC Delco though, I bought the first one (rebuilt) from Blend Air out of Texas, and after that one went, I bought a new one from the same.

It is possible there is trash in the condenser from previous compressor failures that keeps taking out subsequent compressors. It is strange that you do not see any debris on the orifice tube though.
