Can anybody tell me what this is? Is is supposed to be there? It's a clear hose that runs along the A-pillar and up into the ceiling. I followed it down behind the dash and it literally just stops. Anybody have any ideas? At first I thought it was some sort of drain for the moon roof, but now I'm just stumped

 

Is it an aftermarket sunroof? If so, thats exactly what it is.

 

That would be my guess as well. Better lengthen it so it drains outside the car and not under the dash.

 

Thanks for the input guys. I definitely will have to make this drain outside of the car.
