...I can't see where window leaks would end up in the rear footwells.
Where d'ya think it's gonna go then...
Lol. Only joking... But in a car without a sunroof it's more than likely window or door seals. My car leaks through the mirror holes in the door glass...! (Yes, the mirrors are fitted!
) And the interior door handles...! And the aforementioned door/window/hatch rubbers...! And the sunroof! And the windscreen...! (New screen going in on friday
.) And, with water, the only way is down. My car footwells are like a lake after a downpour... All on the 'to do' list...
Hope you get it sorted. It's the quickest way to spoil a lovely car- stinking mouldy sodden carpets.
