So is water managing to bypass the seal of the opening window, travel along the channel the opening-window sits in, and trail off in to the van?I have had a closer look under hose pipe spray to the roof of the van this evening (10:30pm) and the leak appears to be from the bonding of the opening tray runner from the newly fitted flush window we had fitted last week. The leak appears to be from the corner of the opening tray and running down over the carpet and causing the damp area on the ply, our driveway is sloping so this is exaggerating the leak and running back along the wheel arch.
I am calling the fitter tomorrow, very disappointing at the moment as we travelled a long way to have it fitted last week by the best on good authority, any thoughts how I can stop the leak in the short term?

Do both sides leak?
If so, I wonder if your fitter will blame the unit as opposed to their fitting skills.
I have flush sliders too and haven’t noticed a leak, but then I don’t have carpet lining nor a wooden floor..
I’ll give mine a whirl and let you know if they leak.
In the meantime, you could try rubbing WD40 in to the window rubber - I was told this causes the rubber to swell, so it may provide you’ve with a temporary solution (but check with the window fitter first, in case this ends up affecting your fault claim).
