Hi, I am wondering if someone can give me a feedback on why my 2003 honda civic (2 doors stick shift) leaked the air condition cooler gas. I no longer get cold air and I don't even hear the air condition turn on or kick in and start as I use too before. A friend of mine with the same car seems to have the same problem. I know now that I can go check it out at pep boys for $35 and they can find out where the leak is, but will someone tell me how to trouble shoot this myself so I can possibly find it and fix it myself? thank you so very much!!
