I have an R reg fiesta 1.2zetec and a t reg fiesta courier van. I seem to have the same fault on them both, where there is water getting into the passenger footwell. The water is coming from behind the dash board somewhere, I don't think it is from the windscreen seal. The van is quite bad as after heavy rain there is an inch of water in the footwell. As this is happening to both the fiestas, I was wondering if it is a common fault and/or easy to repair?
