I'm not really sure that Climate Control would be the appropriate section for this topic but...
Yesterday as I was running errands, returning to my car I noticed some wetness underneath my muffler area. When I got home I checked it out and it is water, but should I be concerned about the amount of water in that area? It appears it has left visible marks in the shape of an L on each end of the muffler. Could this possibly be condensation from the air vents in the back seat?
