Honda Pilot Wet Carpet from Leaks

I have the same wet floor on the passenger side. I removed the interior trim and took the nut off the fusebox so I could pull it back and see what was happening. I found a round hole on the vertical surface that is approximately 3/4". When I pushed a rolled up paper towel in there it immediately was saturated. I then put a popsicle stick partway in the hole and water rolled out. It is clear there is a cavity behind that hole and it is filled with water. When I drive it comes out and soaks the carpet. It was hard to tell where it was coming from until I pulled the fusebox away from the body. I don't know if there is supposed to be a plug in this hole, and if there is a way for the water to drain out of that cavity. Will take outer body parts off on the next dry day to try to figure it out, but that is definitely where the water is coming from in my Pilot. Please comment if you have the same issue. Thank you.

We had a problem like that years back on a Taurus. Turned out to be a seal related to the outside air intake ahead of the windshield. Might also check around the inside cabin air filter.

It sounds like you have a plugged drain in the fresh air intake cavity (under the wipers). This is a common cause of wet carpets in the front of the car. Very often you have to remove that front grille to access the drain. The terminus of the drain is usually in the middle of the firewall, behind the engine. If the drain hole is plugged, which happens when debris gets in there from parking under trees, etc., then you are driving around with a fish tank---this cavity is not meant to be waterproof, only water resistant, using rubber grommets that hold wires and cables, etc.

Other common issues would be clogged sunroof drains, which are easily tested by opening the roof, looking for the drains in the rails, and pouring a little water into them--you should see the water exiting immediately from underneath the car, usually behind the front wheel and in front of the rear wheel.

I had wet passenger side carpet on my 04 pilot. I read the comments and removed the seat, and glove box. The carpets were soaked. Water was dripping from the ac unit. I opened a small tab and water poured out. Removing the metal piece behind the glove box, the small tab was part of a door to access the cabin filter. I pulled the filter out, It was filthy. TOTALLY CLOGGED!! I cleaned the filter real good and dried out and cleaned what i could. I 'm thinking this may do the trick. The drain was working from what I could see on the ground, but the filter was so clogged it he'd back water from the drain. At least I hope so. Time will tell.

That's typically the issue when you see wet passenger side carpets. Kind of a maintenance issue rather than a "defect". New posts in topics like this are my reminder to go check mine

I'd bet you've solved the problem!

You CLEANED your cabin filter? Actually you are supposed to REPLACE it I think every 30,000 miles!

They are made of pleated paper so I'm wondering how you were even able to clean it!
