2004 Chevy Suburban Wet Passenger Side Floor After Heavy Rain (Part 1) 

Thanks. Check out 2 door bros on here, he found a drain flap behind the over flow tank. It was full of stuff and not letting the water out. I'm going to check mine to see if it's my problem. Awesome job on the video by the way. Keep them Rollin. ✌

Awesome video, my 02 Suburban is doing the exact same thing

Good you found the leak and we will see what you do in pt two

I just love that truck

If you take the fender off theres a flap for a drain that goes under the wiper blade and out down under the fender and when it backs up leaks into the dash
