This happens when it rains or I wash my car. I don't think it has anything to do with AC drain. I know it has something to do with the gutter under the wipers; there is a foam block over a space when you raise the hood on passenger side; also I noticed a puddle of water on the drive when I ran the water hose over the windshield.
I have standing water under the rug (front & Back) on passenger side of car. on 2002 Lincoln Town Car
Do you have a sunroof? If so the drain tubes are clogged. If not check the door seals - have a helper run water while you sit in the car with a flashlight looking for leaks.
Thanks I will do that
