So there has been this puddle forming in my back seat and hasn't stopped. I assumed it was coming from the back (bad assumption) it's coming from a broken ac line under my dash near my ecu. Anyone know where its supposed to connect to? There is a small hole in the firewall it fits, but im not sure if it's just supposed to be pushed through or something. I'm really lucky my ecu isn't fried. Please can anyone help?
