Hello All, this is not a performance related question. It's simply a comfort related question. I have a 1998 200SX SE-R and noticed just the other day that my air conditioner no longer blows out cool air. What do I need to know to refill my A/C? Can I do it myself? What can I do? I'm hot and it is affecting my driving and that is a dangerous thing. I refuse to wear a headband to keep the sweat out of my eyes. Your help is greatly valued. Thank you all so much.
