I think I have a cowl leak in my 2006 E450. Occasionally the carpet in the driver side footwell is damp. Not soaking, but damp. I read that there are old threads that address the issue, but my search has not found them. Can someone point me to a relevant thread?
I also must have some kind of small leak around the windshield. In a rain, while driving, I get a drop or two falling on my right knee. I bought a tube of 3M windshield sealant, but I'm not sure I'm competent to use it. Any suggestions on this issue would also be appreciated.
Thanks
Using "firewall leak" as a search phrase brings up many results; this might help:

Ford has been well aware of this problem, and issued TSBs on leaking firewalls during multiple model years and on multiple Ford vehicles; you might want to check with a Ford truck service center and have them pull up the specific TSB for your model.
Thank you.
