My passenger side carpet would get damp during rain and I traced the problem to the seal for the rear of the water deflector in the door panel but I didn't get to it. Last week, the passenger side front carpet got SOAKED! I noticed a drip on the sill below the door speaker. I suspected the seal at the front of the door had gone.
I just took apart the door, removed all the gooey sealant and reassembled with new sealant. The old stuff was clearly not working across most of the bottom of the door. It had gotten dried out or something and wasn't nearly as gooey as the rest of the door. It looks MUCH better now.
The sealant I used is 3M Windo-Weld Ribbon Sealer, PN 08611. I got it at an independent auto parts store (I don't remember the name). I have seen something similar at AutoZone but it wasn't 3M. After seeing the OEM stuff dried up, I wouldn't use anything but 3M though.
Thanks to all that have posted write-ups in the past and/or other great advise (archon, haro, ddalder, etc).
I didn't take pictures because there are already great photos in various threads.
Now it'* time to go after the leak in the trunk.
It started a couple weeks ago.
