I have an '05 Z-71 Tahoe w/ sunroof. I believe the rear two sunroof drain tubes are clogged. I've located and made sure the front 2 are clean, but can't find the rear 2 (they seem to be too far back for me to see). Can anyone tell me how to find them? If so, whats the best way to clean them (air compressor, vacuum)? Should I remove the headliner, and how?

Thanks!

 

I'd find where they exit and use compressed air, but be careful not to blow the line off of the drain connection, that and try to remove the debris after you get it to exit the line so it doesnt plug it up again.
