I have a 99 civic dx and the other day it just stopped blowing cool air and started blowing hot air. I went and bought a recharge kit and tested the pressure as they tell you to do at the low line and found that I have just over 100 psi at that point. Any ideas as to what is wrong? Am I screwed because my compressor is shot or could it be something else? And is it best to get this problem fixed at the dealer or go to an independant a/c dealer. ANy help would be appreciated.
