A/c Recovory clogged lines

[Chainsmokerjoe14]

So basicially i just recently had back surgery and a friend was trying 2 do me a favor and charge my A/c because he was tired of riding around with me during the day in fl in over 100degree weather. So he decided to put r134 in there, and it was never converted to that... the compressor is fine. but as far as i know there is an oil that takes the gel caused from mixing r12 and r134 and disapates it. At this point id be happy with anything that will get it working to even where it was before(blowing out semi-cold air abt 20degrees cooler then outside :P) but to peak conditions would be ideal(considering r134 sucks and doesnt cool nearly as well as r12 did when it was legal..) but ya... if anyone has any insight that would be amazing.

btw its a 91 SE Coupe DE motor I honestly dont know what other information would be needed at this time... Audio Engineering is my thing not A/c repair lol...
Appriciate the help in Advance, thank you

A good retro fit would be a flush and fill with the correct oil and r134a but it is not possible to fill r134a into a r12 system without the retro fit fittings. There are shops that carry a product called"freeze" 12 that is a substitute for r12 that is 100% compatable for your ac. Its a little more expensive (and no you can't buy it, only shops can) but that would be the right way to fix it.
