Any helpful information/advice is appreciated. I'm the owner of a 2008 G6, with sunroof. My a/c hasn't been working all summer. I tried adding freon, but after a day, I was back to no a/c. I realize that I have a leak, I just don't know where it is. In addition, every time that it rains, my front passenger side floor gets soaked, and it's coming from under the dashboard on the passenger side. Please help.
