i dont know where to buy R12 b/c i think they quit selling but i have a 90 and i need to know how to get my ac back to freezing cold and suggestions

 

you dont have to put R12 you can do R134a but change the service ports. you should get the system checked for leaks since R12 doesnt just run out it had to of gone somewhere.....right way is to get somebody to put system into a vaccuum fix leak then refill...cheap way is to buy conversion kit thing and just fill it up and it should get cold still
