Hi guys, I was vacuuming my car on Sunday and found a very unpleasant surprise when I lifted the matt for the rear passengers driver’s side footwell.. The whole carpet was saturated with water (when u push your finger into it, u can see water ooze out). For the last two weeks I have noticed the car has been smelling musty, and almost every morning the windows would be misted out. I now know why...

I even got my brother to wet the whole side of the car & then force water into the door gap /seal while I sat inside to see if I could see anything or hear water coming in...but nothing.. The rubber seal on the car (not the door) was even 90% dry.

So i’m asking whether anyone knows a possible cause for this? I don’t want to sell the car just yet, so if i can fix this would be great.

The carpet side of the mat was pretty dry, but the rubber side was wet
