If the interior of the car, seat, carpets were soaked, I WOULD NOT PICK UP THE CAR.

It is very good that they found an issue, and have gone on the record with a repair.... did your work order state "windows rolled down by themselves, interior water logged" or similar? There are two elements you want to establish- the windows rolled down and the car was at fault...AND that the car was waterlogged.

When you pick up the car, you want to have them specifically document what they did to address the latter issue...just running a fan will NOT do it. Once water is in the carpets the interior must come apart. Furthermore, issues that result may take weeks/months/years...AND the dealer can absolutely deny that these issues are the result of this singular event. You need to get it fully repaired now.

IMO
