hi all, im charlie, new here and seeking some a/c help.
i ham having a mystery issue regarding the installation of a new compressor.
the original one finally failed, ive so far installed a new compressor, condenser accumulator and lines. once the recharge is started, with only one pound of 134, after a few cycles and about45 seconds the freon lets loose through the blowoff valve in the back of the compressor and the clutch seizes. im on my 3rd compressor. no blockages have been found as of yet. im kinda flustered, can anyone provide any clues?
thank you.

Welcome to the forum from Oregon.

Like @Doubeleive said, is the compressor an exact match? Did you replace the orifice with the lines? I assume so but I don't like to assume. Pics of old and new compressor? I assume again that you got this compressor: https://www.rockauto.com/en/moreinfo.php?pk=83161&cc=1166374&jsn=2222

You did not offer a year and make and model so I looked up for the 92yukon in your screen name.


We recommend that you put all your rig(s) info in your signature so we all don’t have to guess at year, make, model, engine size, trans, rear axle locker…….etc. While you may have posted pertinent info in your first post, you may forget to do it again and the info is needed by us anyway. Makes it way easier on all members that attempt to help, to have that info right up front. It is also recommended that you take a pic of your RPO codes, on the inside cover of the glove box, and post that image in your signature. All this info will greatly help those that will try to help with a problem.


If there is any other info, like upgrades, mods or recent mechanical/maintenance work done, that would be helpful in any post as well. Too many times a question is asked by the poster and after about 10 responses we find out that the poster has done recent work to attempt to fix the problem or work that was done that SEEMS not related to the problem.

THE VEHICLE IS A 1992 2 DOOR GMC YUKON. I DID NOT USE AN AC DELCO COMPRESSOR. IVE ALSO NOTICED THAT THE ORIGINAL CONDENSER IS ALMOST 2 INCHES THICK AND THE REPLACEMENT IS JUST UNDER 1 INCH.

First: No need to capitalize all letters/yell during a post.

Second: The thinner condensor is because of R134A and how condensors are made for that. They are a way more efficient design. Aftermarket NEW compressors are suspect as well as reman compressors. It's your money and can spend it the way you want. Also, you did not answer back about the "exact match compressor" that @Doubeleive asked about.

I was just wondering if you used the same type of design compressor, brand doesn't really matter but there are several design differences so they should match up the same

Seriously so did I have in mind that if the oil separate and clogging it or get cold and
tough like cold butter. You never know now this days what you get and if you have a cheap mix you filling with or buy no name oil on ebay and topping it with you can make a mess in the end.
And the grammar in my first post wasn't pretty, I can better. :D

I gotta take mine to the Toyota dealer to get it repaired knowing the GM dealer will use the mechanical a/c machine on my electric a/c (OILS used are different using the incorrect oil type will damage it) :(

When he completely opened the system the need for a vacuum recovery is no longer there. He may have just let it go to the atmosphere. The old oil is in there except for what was in the bottom of compressor and accumulator and the condenser. Those were replaced and now system will need new CORRECT oil. I am still leaning toward the wrong compressor because he still has not answered that question put to him. Yes, he still has to create a vacuum to recharge and he did not say he did that either.

I have. 93 Silverado that I had an issue with as well but found what the issue was. On he high side of the compressor, if you compare it, you might find that it's slightly lower than the low(suction) side. After three compressors, I took the compressor in and showed him and compared it to the original to show the parts guy. The resolution was to get another one, buti made sure that the seal/O-ring was thick enough to compensate for the high side being lower. It worked and yes, I did switchf R12 to R134. Yes, I did vacuum the lines as well.
