I pulled the seats out to refurbish them today,and found that the carpets and foam underlay in the front foot wells are soaking wet. I was afraid it was antifreeze, but it turns out it is simply water. However, I can't figure out where it came from. If the drains for the sunroof are plugged, would water find its way into the footwells? Is there another place where water will enter these cars, like from the firewall, vent cowl, or underneath?
TIA
