I am trying to refill the freon in a 1999 murcury tracer, can someone explain to me where the a/c port is

ummmmmm put the freon down sir and step away from the vehicle. if you do this incorrectly you can hurt yourself. pay a trained tech to do it and check the system. Show me an ac system thats low on freon and Ill show you a car with an ac system leak. you dont use it sir if it goes away that means its broken.

first are you certified not everyone can do hevty fine
