So i just picked up an 87 mr2. Its the oldest car ive ever had and the ac blows hard but doesnt get cool. It appears all of the ac components are still in the car but i dont know if its on old refrigerant or on 134a. Is there a way to tell? Did these already have the new stuff? I know nothing of ac equipment so any help is appreciated.
