I have the exact same problem...did you get a reply or a way to fix it? thanks
Our Jeep after a rain will have standing water in the passenger floor board. after much investigation, we have noticed a hose that runs along the upper "body" passenger frame. when you open the door, you remove the plastice that goes along the inside of the door opening (of the body of the car) to the dash. there is a hose that seems to be rotten, becasue when you try to move it it just breaks and crumbles. we haven't removed much of the upper interior to follow the hose from begining to end, but it seems to run toward the rear. Not sure if it has anything to do with the moon roof. But when it rains it leaks from this hose. we want to sell the jeep and don't want to dump a lot of money into it. any suggestions? thanks!
