AC Compressor Groan
The ac compressor on my '85 Burb is getting pretty loud, more so at idle. It blows cold but the groan is getting unbearable! Any ideas?

Re: AC Compressor Groan
Good Morning, Most likely the bearings are bad, that would be my first thought.
God Bless, Terry |

Re: AC Compressor Groan
It would be a great idea to go ahead and get the compressor replaced before it locks up and comes apart internally sending trash through the system.

Re: AC Compressor Groan
Thanks, I'll be looking into a new compressor and orifice tube. I will still have to check on the reason why the previous owner cut off and capped the rear ac lines. I have a feeling there's a leak back there somewhere that they didn't want to fix.

Re: AC Compressor Groan
It could very well be because of a leak from the aluminum lines running from front to the rear. Had that experience with a 97 burb. Ihad to replace both lines front to back plus the rear evaporator.
