Damp floors

["Ross O'Shea" <Ross.Oshea@med.monash.edu.au>]

Hi Volkspersons.  

With the winter rain we've been having here in Melbourne, the 
notchback has turned into a bit of a swimming pool.  Water seems to 
be getting in via the heater vents on the floor, and now the carpet 
smells like it's rotting.  The water collects when the car is parked 
(I normally have the heating on when I'm driving any distance, once 
the engine has warmed up, of course).  Does anyone know how this 
water is getting in and what can be done about it?  I really don't 
want to end up with rusting floors!  

Cheers,
Ross
