Hi Kevin,
I read with interest your posting as I face exactly the same problem with my Espace ie water on the floor on the driver's side. We tried to clear all the ventilation outlets and other obvious causes but to no avail. Two replies suggest it comes from the quarter light glass. Did you try to replace it ? Did it work ? If not, did you find another solution to this most annoying problem ?
I know it was a long time ago but if you could help with this it would be much appreciated. Thanking you.
