Replaced all O rings, accumulator, orifice tube, hoses, and a brand new 4 seasons compressor. Also swapped out the cycle switch for a 134a rated one. I pulled a vacuum in the system for over an hour. It held 29 inches for 24 hours. Charged it up with 3 12oz cans of Freon.
I’m currently sitting at 60 degrees coming out of the vent. My accumulator is sweating. Condensation is dripping from my truck. When i put it on max AC it blows for a second, I hear a door flip open and the air out of my vents sounds “harder” and it starts getting colder. When I turn it off I can hear a spring returning a door. My hot and cold lever seems to work well as well.
I was just wondering if anybody had any experience, thoughts, or input to try and get me closer to the 30 degree range.
Thanks,
Ryan

Never gonna get 30 degreens, but I've got to get my 83's AC straightened out so I'm interested in what all you did.
Have a link to the compressor and hoses you used?
My system blows cold when charged, but I have a leak that appears to be in the compressor. It's an R4 and from what I've read they're almost not worth replacing they're so failure prone.
How many orings were there in the system? What kind of flush did you use?
I haven't worked on GM A/C before. My old Jeeps all used flanged fittings with no orings.
