2002 Yukon Denali XL - Wet 2nd Row Floor boards

[02denalixl]

I have an 02 Yukon Denali XL that is experiencing wet floor boards in the second row captians chair row. The carpet is not wet but the padding between the carpet and the floor boards are wet. I used a shop vacuum to remove 1/2 gallon of water. I have no idea where the water is entering the vehicle...do you have any suggestions where the water is coming from?

No, I have no suggestions other than... sometimes where the water ends up accumulating can often be a distance from the actual water entry point. It all depends on the angle of the floor pan, etc. You'll just have to water test to see if you can find the entry point. Pulling ALL the trim helps because water can run under the trim pieces making it difficult to find the actual point of entry.

I have no idea what could be causing this but i had a similar problem in an old volvo I had. The floor in the back seats was wet. turns out the drain tube for the sunroof was clogged and the water was backing up and somehow getting into the back seats. It was a complete mystery to me but it does go to show what gm-tech said above. The water almost never pools where it is coming in from. In my case, the actual leak was a good 5 feet away from the water itself.

I have a similar problem I just uncovered in my 02 Suburban. Passenger front and rear floors were soaked! Its only on the passenger side, and only front and rear of the front seat riser!

I pulled the front seat, rear smaller split seat in order to pull up the carpet, and vacuumed as much of the water out as possible. I also pulled most of the trim on that side to look for leaks. Nothing obvious.

I poured water in the sunroof frame, and it drained correctly under the truck. I'm wondering if water could be forced in from underneath the front seat pan, which could cause the front and rear of the pan to get wet. What a pain!

 

I did have an undercarriage wash recently, so I'm betting its related to that if I can find a seam underneath.
