As a new owner of a 2002 2.3 Ghia manual with what seems the perennial wet carpet syndrome I trawled the various threads on this (and other) forums. First find? rear washer pipe connector dislocated. Great, I thought, sound deadening underfelt cut out and put to dry whilst I successfully sorted the connector and monitored the situation. Didn't need to wait long, with the current weather - still water ingress! :-( Scuttle drains checked, wiper assembly stripped out, scuttles fully cleaned of 12 years of crap and pollen filter changed. Time to monitor again... STILL getting a wet floor but at least the carpet is already up! OK, search behind the glovebox revealed... nothing, dry as the preverbal bone. So, a watering can of water down the windscreen and over the scuttle area and another hard look and... Lo and behold, weeping from behind some of the panel sealant at the welded seam between the wheel arch and the heel board. I cleaned off the old sealant and it became apparent that the problem had probably been present since the body was assembled! All cleaned up, dried up and new silicone sealer injected into the seam and now we wait...
