Drain tube under carpet?

[Greg63]

My 2013 Model S sunroof keeps leaking and it seems the only fix is to replace the top with a second gen top at around $4k. I've decided to disable the roof (pulled the fuse) and put a sheet of PPF over the entire roof. That should equal no more leaks and still look fairly good.

This last time my carpet got soaked really bad. I pulled the carpet back to let it dry out and found a black tube that comes from somewhere in the dash and terminates under the carpet. Doesn't connect to anything. It looks like a drain tube. It's the same on both the driver and passenger sides.

Does anyone know what it's for?

Went by Tesla since I had to go into Charlotte anyways and they said it is a breather tube.

I remember seeing it when I installed the Illuminated Door Sills on my Model S (since I didn't go with the installation instructions route), but didn't think much of it. Everything was dry and it had no signs of any liquid ever coming out of that tube (could be a good thing, could be a bad thing), but I left it alone anyway.

Good to know what that tube actually does.

Thanks @Greg63!
