Anyone able to tell me where the sunroof drain lines end on a 2006 z71 Tahoe? The truck has been through two severe rain storms and is parked on a downward slope in my driveway. After each storm, the carpet on the passenger side nearest the door jamb is wet but I'm not able to find where the water is coming in. Any help on where the drain lines are so I can start by cleaning them would be appreciated. Thanks

 

This doesn't say where they end but it might give you some guidance as to where to look for them...

Thanks so much for the reply, quite helpful. I'm imagining that pulling off the trim pieces is literally just pulling them off the clips and not some other special process right?

 

It should be, you local auto parts store as well as Amazon.com have some tools that make removing body panels and molding easier....
