As it's getting hotter here in the midwest (finally) I will be needing to put my A/C on more and more. I tried to the other day but it wasn't blowing any colder than it does with just the fan (the A/C on my 2.0 was ice cold). What made me more concerned was that when I did try to turn the a/c on, I noticed a very loud watery sound coming from under my car as I was driving. It sounded like a sink faucet. I turned the A/C off and the water sounds went away. Turned it on again, the sounds came back. It's not getting cold either. What could be wrong with this?
