I too have experienced a major leak only on the passenger side. They do not know where it is leaking. I took out about 1/2 gallon of water from under the soaked carpet. Ford told me to watch it. I have 33,000+ miles almost past warranty. I just went thru a rain today and noticed water in the back passager side, but not the front. I noticed a few others have a similar problem. Has anyone been able to get this figured out yet?
Why is this leaking on the floorboard?
Thanks |
