Crew Cab Leak
2001 7.3L 4x4 328,000 mies
I have the crew cab? (rear doors open opposite to the front) anyhow whenever it rains the carpet under the rear seat is wet. Just wondered if this is a known issue, with a fix or just something random i'm going to need to chase down

Not sure if it is a known issue but my first thing would be to sit inside and have someone shine a flashlight in the door edges while you look for light. If it is getting that wet, then there is a significant leak. But first check with the flashlight to make sure it isn't a weak or loose hinge or a bent door. Then second would be to replace the door seal.
Another trick, if you can get the equipment, is a portable smoke machine. Fill the cab, turn on A/C and close the doors to see where it is coming out.
Then there is the dollar bill....close it in the door and see where it slides through real easy.

If the rear doors open opposite ('suicide' style) then you have a Super Cab. I'm not sure if it's the same arrangement as my Crew Cab but there's a plastic trim piece in each corner that runs from ceiling to floor (it houses my speaker). It is not too difficult to 'peel' back that trim piece (unbolt the top of the seat belt and IIRC the rest of it is press-fit pins...there may be a screw or two in there somewhere) to see if you have water leaking down there from the roof. I have read where people have had cab leaks from deteriorating rear window seals and the cab corners (under the plastic corner piece) on the roof.

Where under the seat?

Do you have a sliding rear window? Mine leaks and it shows up at the back passenger door sill, under the plastic step that's removable. I couldn't figure out why it was getting wet there last winter and pulled the carpet back and found the path of water running from the sliding window all the way to there. It didn't cause any other area to get wet. The water has a perfect path to run along the edge of the cab to that low point.

Another idea: Make sure the rubber seal at the cargo/third brake light is in good shape and be sure the screws for it are tight...

One more trick to finding leaks is to pressurize the cab with a blower fan. Roll the window up on the blower fan and stuff a towel around the Fan to close up the gaps. Spray the suspicious areas with soapy water from the outside and it'll bubble.

This is a poorly designed POS from Ford, with a non-replaceable gasket (the gasket on mine is hard as a rock). I think it's one of the reasons you see the cab corners rust out on some trucks - water leaks down and around and ends up in the rear cab corners.
