Mysterious water leak please help
So I towed my boat to the dealer to get the crash damage repaired tonight without an issue. My wife and I then went to get a bite to eat and when I came back outside there was a trail of water coming from under the truck. I got a flash light out and started looking for where it was coming fom. I narrowed it down to the passenger side by the fire wall. I was able to get a drop off the frame rail and it is not coolant just plain old water. It is like the air conditioner was on high on a mid august day. I had the heater on so I just can't seem to figure out where it is coming from. Any and all help will be appreciated. Thanks again.
