BISCUT

Mine was the rear brake light saturating my front driver side. New brake lite housing and no more leak!

Could you possibly get me some pictures of this plug? Thanks!

I have this same problem but passenger side, front seat. Is this the same thing? Pull up the carpet and seal the holes Ford only put tape over?

Looks like I fixed mine finally!! There's a long foam thing that wedges inside the fender up by the cab. It runs from the windshield to the mudflap. I noticed mind was loose and not sitting snug in the fender. I used a stick and pushed it back into the area. Here's a pic, it's the grey thing. (not my spray foam attempt to fix this leak lol)

Ok.... maybe I'm not following exactly what is meant here. When you say the "rear brake light",... how is the associated with the front seat floor? Is there a rear brake light wire harness coming throught the firewall that leaks, or do you mean something else. Pics would be nice if possible.
Thanks

Duane

Thanks 08f150xlt.... I'll have to check that foam seal on mine.

Duane

By the way, I did pull carpet back and silicone sealed the bolt that comes through the floor and the entire area where Ford put tape coverage on. STILL LEAKING.

Duane

Here it is.... from 4x4angel.... what do you mean by "3rd brake lights"?.... is there a wiring harness cannon plug leaking at the firewall somewhere or just a seal where the rear brake light wiring comes through?

I have the same thing happening along both the driver and passenger side. This summer, I plan on ripping out everything and waterproofing it all. Should be a fun little adventure.

Take a look and see if those long foam pieces are in place, maybe they both have been tossed, I noticed mine wasn't right and I'm assuming it was from when I had my pass side manifold fixed. They had to remove my fender well to do that. You'll see this foam strip if u remove your inner fender well. I'm guessing it wasn't put back in the right way... Easiest way to check is just pop the good and check up in the top corner under the wiper cowl and see if it can be pushed back further than where it sits now... That's what mine needed.
