hi liz,
i know what u r on about and does the water in come to the front footwells or the rear? is the car parked on a hill? if your water leaks getting bad, its the door regualor inside the door, u need to remove and reseal the regualor, if the leak is still there then u need to reseal the rear doors aswell! any more problems, just let me know ok.
hope that helps liz.
