Anyone here have an idea of what the tube in the passenger kick panel is for on a 06 Lacrosse? I tracked a wet floorboard to that tube leaking water inside the kick panel by pulling it out and putting it in a bottle while it rained. It couldn't have been designed to pour water in there because there's no drain in the kick panel. When moving it back and forth I can't tell for sure if I can hear it in the a pillar, but definitely hear it in the top part of the dash close to the a pillar. If it's connected to the sunroof that wouldn't make any sense either.
