I have a 97 honda civic and the A/C isn't blowing cold when its hot outside (its blows cold when its around 70). I figured it may be low on freon since the high pressure side fitting is dirty and has leaked a little. I fixed the leak by reseating the valve guts. Well I hooked up some freon and it was barely low. I added some though and it didn't help. The compressor comes on like its suppose to. Not sure what could be going on or what to do next to fix it.
