MONTE CARLO Factory 1986 AC; where do I start?

I just replaced my r4 compressor. The hoses
Condenser core and orifice tube flushed and with new o rings using 134a. It's blowing 33 degree air out of the vents

Does the compressor Turn or just the clutch. Good question LOL. I don't know what I was thinking. I spun the clutch And said to myself, yep everything works great.

I have no idea the compressors any good. Yesterday I installed the belt but, did not engage the air conditioning because I'm not sure if there's any lubricant in the system.

I'm not looking into aftermarket AC systems anymore.

I'm bringing the car tomorrow to a AC guy who will convert the system to R134a. He says, as long as the rest of the system is functioning it shouldn't take long or cost very much.

Unless there was a catastrophic failure and all the freon rushed out in one big whoooosh, then there would be oil in the system. At rest it tends to puddle in specific spots like the compressor. In operation it gets carried along with the freon. Probably a smart move handing it over to a real AC guy. He is right- if the system is sound, which it certainly looks to be, then it won't be a big deal to get it converted. Some things will need automatically replacing like the receiver/dryer and perhaps the compressor if it leaks or is shot. Other than that he will flush the system to get the old oil out then refill with PAG oil. The he puts adapter caps on the service ports and charges with r134a. Enjoy the coolth!

The A/C's fixed and blowing 40degs; so nice. The tech said a few compressor gaskets and a conversation is all it needed. Sadly, the vent selector is stuck on defrost. The vacuum line melted due to being near the exhaust manifold. Easy fix.
