leaky 4000Q!

[Bob]

I have a water leak thats driving me nuts...

Its outside water (rain) that leaks down onto the carpet...  Seems to be
coming from furthest right hand side of dash, to the right of the
glovebox even, but not on the A pillar.  The A pillar isnt wet, and the
sunroof drain *APPEARS* to be working OK. (I can see the hose in the A
pillar and water is flowing through it.)  WHats left? Windshield? I cant
see anywhere that leaks...  Its not coming down the firewall either it
seems... it looks like its coming right from the ECU area!

Any help appreciated.
