So I am trying to troubleshoot a "leak" in the floor of my ZHP
My 2004 ZHP is not my daily driver anymore so it sits more than it is driven. But it is my airport car because it can fit in a small(er) parking spots.
So my last trip during the holiday, when I returned it was super cold so I turned on the rear defroster. It did not defrost the whole window, only little "strips". I thought the defroster was going, but when I got home and investigated, the issue was lots of moisture on the INSIDE of the rear window.
But the back deck was not wet, nor were any of the seats. I lifted up the floormats on the passenger side (I have the original rubber BMW mats) and nothing front or rear. But on the driver's side it was sopping wet both front and rear!
The windows weren't "cracked" open a bit or anything like that, and if they were, I would have expected wet seats. I went home and tried to soak up the water with towels. There was quite a bit of water in the carpeting. To really dry it out, I laid down paper towels and then spread out rice on the towels, covered it with another layer of paper towels, and then put the floor mats on top of the whole thing, trying to force the moisture into the rice kernels. After two days, lots of soggy rice in between the paper towels!
I then took a hair dryer to dry it off completely.
So now the frustrating news. I took the car out for a drive on a rainy day and checked the floor boards again the next day. Sopping wet again in the front driver area, but nothing (thankfully) in the rear driver area.
I think I have a crack in my floorboard and am going to check it out.
Has anyone had this happen to them? I don't think it is coming from the engine compartment, because the "top" of the carpeting in the footwell area is dry. it is only the bottom that is wet.
