you must take in to a certifed ASE mechanic as it is illegal to do it if you are not certifed

That is an out and out lie! If you can prove it I will apologize. I believe you should research the law and you will find out that anyone can change their freon, R-134a is available at most parts stores and in stores like Wal-mart, if it were illegal it would not be available to the general public.

To answer the question, find the low pressure port and while running the engine put the freon in till the gage say it is good makesure you have the A/C on max...
