So that is what those are.* When I pulled out the rear cup holder and cubby, I saw a rubber hose running down in front of the wheel well.* I wasn't sure what it was.* Learn something new every day!

Mine was leaking through the On Star mic one time after a heavy rain fall.

Thanks for the info F5 !!
It makes perfect sense now of why I was getting the water leak in the cargo area passenger window. From your explanation, seems like maybe the hoses weren't run correctly. I'm almost happy they found this as the problem area since I was convinced it was from the recently replaced roof rails! Guess that's why I'm not a mechanic!

Thanks again
