If, like me, your sunroof drains are blocked and you're getting a wet head or feet.
I found a quick and simple way to clear them with minimum dismantling or hassle.

Buy one of these drain augers (1/4" diameter)

Run it down both front drain pipes from the sunroof until you hear the water trapped escape and run onto the floor, or remove the side vents and take a look if you feel the need. I did this and cut back the foam a bit to allow the tube to sit out without being distorted.
Much more effective than a bit of wire or cable. Can then be done every 6 months to prevent build up, worry gone.

I found a length of stiffish garden strimmer cord "rodded" them out quite well, put a couple of little "barbs" on the lower few inches, I removed some rotted "leafy" looking material from mine.
