Where are the drain holes & how to unblock them in a clio sunroof

Hi from uk the sunroof water drain holes are situated within the gutter below the sn roof surround seal and are both at each rear corner/s of sunroof to un blocktry a length of wire preferably plastic coated and poke the wire and twist as you push in drain tubes then use a small water can as u would use for indoor plants and pour hot water gently into the gutter if main blockage has disturbed ? hot water will/should flush the drain tubes thro you could also continue poking with wire too ? i use a length of wire from house lighting 1;0 mm" use either live or neutral wires (insulated) this always works for me TIP! when you wash car raise sunroof and clean gutter channel with rag to prevent dust collection blocking holes/drains in future
