do not use rebuilt compressors from anyone, I just went through 3 from auto zone for a customer and even that one just went out.

it was a rebuild compressor from auto zone may be they honed the low side to much,think will replace the compressor what do you think

I actually could not get the line new, I had to find a used one on Ebay, ugh! Could be the compressor o-ring sealing surface is faulty, never know!

thanks hard to find a new line but sounds like that might be it.the second o ring was a OEM the first was the one that came with the compressor.wondering why it didn't leak with old compressor

IF you used OEM o-rings to try to fix it, then it may have a bad o-ring sealing surface, may need a new line or component, depending on where the leak is, had this issue with a '99 Nissan that would not seal either until I replaced the components.
