This happens whether the vehicle is in motion or not and after testing with a garden hose, the water seems to be entering through the firewall or maybe near the drain near the drivers side fender. I have also found references to a factory problem with the E-450 and a weld in the chassis, but upon speaking with a Ford representative, as well as searching the Ford TSB's, I cannot find the service bulletin. Has anyone else encountered this problem, and what did they find to be the solution?......Thanks
