Wet floor board

[Lindsey8999]

We purchased our 2010 Commander in 2009, however in the dry Mojave Desert. Now we are in Oregon. Initially I thought my water bottle had leaked, however it became evident that after each rain, the floor board would become completely SATURATED! I have brought it to a local mechanic who appears hesitant to touch the issue and referred me to a window guy. I emailed the window guy and he says he doesn't do leaks. Outside of taking it to the dealership (which I would like to avoid due to higher costs), I have no idea what to do! I have pulled up the carpet and the water appears to stay only within the passenger's floor board. There is no evidence it is pouring down from behind the dash, as that portion of each pad and carpet are still dry. It's almost like it is bubbling up from underneath the floor board. Either way I need to get it fixed! The mildew becomes a real issue, especially with a 2 year old in the car with me.
Any advice would be helpful!

First get some mildew spray and treat your carpet. Second and most common cause is clogged drain tubes from the sun roof you can find the how to on here. Don't have a sun roof then you have some investigating to do. I had the wife spray the jeep with a hose till I saw water coming in then followed it up. Other causes have been secondary door seals, leaking front window and side windows and roof rail bolts. Good hunting!

Drag! I was afraid of that! We don't have a sunroof, which the mechanic said he had hoped for, because that would be a likely culprit. Ok, so if I start from the bottom up, from the inside of the vehicle, can I just get some sort of water sealant and start plastering any potential "plugs"... which there is one, a little black one... and interestingly enough, it lays about even with the horizontal water puddle stain.

If it's a door seal, how do I fix that?

I would just assume hit all potential problems at once and not wait until the next rain.

Oh, if it's a leaf blockage in the "hose" how do I check and clean it out? (saw this on a different post)

The hose is for the sun roof drain. Don't worry to much about fixing it untill you figure out where it's coming from. Peal your carpet back get in there shut all the doors and have someone start in one section and just hold the garden hose for a minuet before they move until you see the water coming in. Then pull the panels working your way up until you find the leak. Most all the panels just pop off and dropping the liner enough to see isn't to hard either do a search the instructions are here. It's a different fix for all the spots that can leak buy a good sealant like mastic works well. You could back the roof rails screws out put some sealent on them and tighten them back up. if its the windshield you need to take that in. The door seals you can re seal the rubber to the body.
