Sunroof leaking

[woody798]

Hi, I have recently acquired a Toyota Aygo 2007 with a sunroof installed from factory. I now have a water leak. Water appearing on the underside of the sunroof glass, collecting on the plastic trim covering the sunroof tracks and trickling down the windscreen. I have read a fair amount now on leaking sunroofs and all the info points to blocked drainage tubes. I can't seem to find any drainage tubes all you can see in the 4 corners is a direct path to the headlining which is obviously where the water is heading. Has anyone had an issue with this? Any info would be great appreciated.

don't think they ever did a factory sunroof, the mk2 had a rag top

Any markings on the glass ?

a pic of the inside sunroof trim may help
