Wet rear passenger side carpet

[royp4]

Hello all,

I am happy to report that my 03 cab was the recipient of a miracle healing. No more check engine light, and it runs like a scalded cat. However, I have discovered that the rear passenger carpet is quite wet. We have had a great deal of rain in the last week. Any ideas on where the leak might be coming from? I see no obvious source. As always, thank you for your continued patience and expertise.

 

Thanks again,

Roy Parnell

Check all your drains.  Sunroof drains are notorious for getting blocked and making the rear carpet wet.  Do a search for drains and then check them all.

In the Cab, there are water collection trays (upper and lower) under the top mechanism on both sides of the car. You need to remove sidewalls (preceded by removing rear seats) to get a look at it all. Top tray dumps into lower tray (the hose can come loose there). Trash (leaves) in either can cause water to leak over low walls of trays. Then lower tray drains through a hose that goes to a one-way valve on the front side of the rear wheel well. This little flapper valve can become gummed up with road dirt, etc. Pull it out for cleaning, then replace carefully. It can tear. While its out, pour water into upper tray and watch its progress through the levels.

 

Hard part is disassembly. Easy part is seeing the likely problem once disassembly is done.
