Recently, it's been hot as hell in the afternoons so I've been blasting the A/C of course. But now I have wet spots forming on my passenger side floor board. My A/C blows very cold and most of the parts are new (bought that way). Why does a puddle form under the passenger side carpet when I use the A/C for long periods of time? When you look under the chassis you can't even tell. What's going on here? Thanks in advance.
