2004 Convertible

I have had this problem myself. There's a Ford TSB about this. The water leaks from an incorrectly sealed seamed between the floor pans and the frame rails.

Here's some of my threads on the subject.

2003 GT conv - Water leaking into rear floorboard


2002 GT Convertible Wet Floor/Leak

I have a 2000 convertible with a drainage problem as well. The water draining off the roof at the rear quarter window tracks on long the edge of the fabric towards the drain channels but ends up dripping off just outside of the rear of the channel. The result is the floor under the rear seat and foot well gets wet. anyone else with this issue? And to answer the first question I 'm always asked. Yes the drains are clear, not that that would affect how/why the water doesn't run off the roof fabric at the proper place anyway.
