1986 gtv6 no Ac

Question for the group. Recently got one 1986 gtv6. Everything works but the Ac. Compressor works fan works blower works and I can actually see the gas on that little bubble on that black part going through. So what the hell? Runned it for 10 miles and nothing. No cold at all.

Did you have the refrigerant charged (filled up)? I assume the original refrigerant was R12 - NLA. The most common currently available refrigerant is R134. But R134 is not as efficient as the old R12. New cars (that use R134) have systems designed with that in mind.

I had our GTV6 changed to use R134. The system is evacuated and R134 compatible oil is added and the dryer is replaced. It works OK but it's not freezing cold by modern car standards.

I think I found the problem. Found a can of R134a. I guess precious owner mixed the gases.

This might help?
BTW if you see bubbles, gas is low.

Can't see your image. Don't you guys think it's better for a mechanic to see it? I'm pretty sure both gases are mixed witch is a big no no.

After reading some posts I got more confused. Apparently first gtv6 models are freon R12, and the last model was with the R134a. Either I read wrong or I don't know what to do.
How can I identify older systems to new ones? Is there any visual difference?

Had another eureka moment.
If the system was R12 why does the R134a nozzle fits?
But if it was changed for r134a why does nothing looks newish.... Everything looks 33 years old.
