Wet floorboard

[Joe406]

2005 Tahoe Z71 with sun roof. I have extremely wet carpet on the driver's side only floorboard. I checked the sunroof drains. I checked the door seals. I cannot find where the waters coming from. Any ideas?

Remove the cowl and check for the sealant under there on a block off plate cover (can't remember the name).

There's a few older threads here that show you that process...

How did you check the sunroof drains? Did you blow compressed air into them to be sure that they are clear all the way down to their exit?

As indicated above by @strutaeng , the cowl area is also often part of a water inside the truck issue.
