Sry for the long post, but I suspect many of you probably can easily identify the source of these leaks, so I tried to give it as much context as possible.
It has been raining in Portugal and I found water inside the car and I am not sure where exactly it is coming from. The carpet bellow the driver's floor mat was kinda soaked. And then I realised that there was a massive amount of water pooled on that little pocket on the side of the driver's seat! I mean, enough to create mold on the wooden handle on the pocket knife I always have there. The pocket knife actually prevented me from seeing there was water in there. ![]() I wonder if it can be from the cracked windshield rubber frame... ![]() ...or from the door not seating right... I know I should fix this, but it's not just adjusting. The door really is bent. I guess the car was broken into in the past and it wasn't fixed properly. A body guy i went to said he needs to cut the door where the arch meets the door and weld it at the correct angle. I tried bending it with a buddy and a 2x4 beam and it would go :s ![]() The car always took in some water from the driver's door corner, mostly when I am power washing it, but never enough to soak the floor, let alone pool on that seat pocket. And then there is the most misterious leak. This one I have to clue, besides maybe some hole on the underside of the car or perhaps a broken back wind washer hose? (even though i though that hose passed through the roof!?) But I do know that hose is no good cause I don't have water on the back washer. Anyway, that sponge on the right corner of the spare tyre space was soaked. Really soaked. I think there was also some water pooling on the metal surface. This photo was taken weeks ago. I did no check again today, but I suspect it is probably soaked again. ![]()

With carpet out sprinkle some talc about the floor/side metal surfaces. When it rains you shoukd see the track the water forms and were it comes from/starts. I assume that there is a large plastic plug in the side panel. It is not unknown for the sealant to deteriorate and require re-sealing.

Also door seals are known to cause this type of leaking The rubber perishes after all these years. They are available new now on Skandix and others.

I've read and it seems that a bunch of issue cna cause water/liquid to pool under the driver's mat. I've read the heater valve and the AC are 2 of them. The heater valve wouldn't be possible because the heater matrix is bypassed, right? Since it is bypassed the coolent doesn't enter the car, right? The ac, I don't really understand how it couldn't cause water on the inside of the car. Either way I did not see any signs of moiture down the walls.
