okay.. like i said i do a $hitload of a/c work.. and i own just about every tool possible for the job.
haha you cannot wrap a freeon leak. lowside psi is 30-50psi and highside 150+ psi.. how you going to 'wrap' that????
what you need to do .. or have done.. is put some dye in the system (pressure it up) and look for the neon green dye leak. if you cant find a leak after looking its probobly either the expansion valve or the evaperator. ...
also a pressure check on the compressor (you can take the compressor off and to a shop that can do this for you). ive replaced like 4-5 compressors on 4th gens now.. what can you say the newest 4th gen is 10 years old.
you still havnt said what year of car this is and i'm too lazy to look in a profile.
