over the past 2 weeks i have been noticing the floor behind the passenger seat where it joins the vertical part of the rear seats has been getting wet and holding water, no idea where its coming from, only happens when its raining. last time i dried it out and put a hose to the trunk drains for about 40 mins and there was no water on the floor, i surrounded the area with dry microfiber cloths thinking that if the water were coming from the door or something that the cloths would hold the water. i left it overnight and the next day while i was at work (it rained for about 11hrs throughout that time) and checked on my way to the gym... towels were dry floor was wet again, car hadn't moved since i dried the floor. I'm at a loss any ideas? where the hell its coming in from?
