New outer rubber door seals fixed my '06 Toledo's wet window.
Dealer didnt give in too easily, but eventually after much argument surrendered to my constant insistence that they change the rubbers under warranty....
problem solved.
I also got the line 'SEAT trying to design new type of door seal....'....crap....replacement with old-style rubbers did the trick.
Obviously some kind of manufacturing defect with the original rubbers on that door....porous rubber or something....i dunno, i didnt see the ones they took off.
