It seems like my compressor is starting to kick on more often and it seems pretty regular as well. My guess is that it is starting to get lower on Freon but I haven't confirmed that yet. I went to a place and they wanted 150 just to take the old stuff out and then put new Freon in. They couldn't even diagnose it for me, just could flush it all and put new stuff in. What does it take to check the pressure in the AC? Difficutly level? Car is an 02GT for those who are on mobile.
