Hello, I'm a custom owner but just recently bought a used 14 plate connect from trust ford. On delivery found water in the drivers footwell but figured it was from valeting.
closer inspection found both foot wells completely water ridden.
Have removed the seats and the flooring and found water under both seats and all sound matting soaked.
Can't find a definitive answer online and ford have told me there is a TB relating to the AC drain off but that doesn't answer the same amount of water in the passenger side
i had a similar issue in an old '98 audi and the problem was the drain hole in the bulkhead where the battery sat got clogged up, the bulkhead filled with water from the windscreen and then overflowed into the footwells where the ecu lived and wrecked everything
If there is a similar cause i would be interested please ??
