Where are the drainage holes for the sunroofs on a 2000 Renault Scenic?

there is a tube on each corner of the sunroof frame, two rear run down back quarter panels which exit behind the rear wheel inner arches, two at front corners exit behind the front inner wheel arches. quick test to find blocked tube - open sunroofs and pour a cup full of water in each corner and look at wheel arches to see where the water is escaping - no water means a blockage,
