Probabliy a blocked drain in the scuttle panel, where the blower motor draws air.

Yes take the covers off and clean all the crap out that will have gathered over the years.

Or it could be an incorrectly fitted pollen filter cover; though I offer this comment based on common reasons for water in the footwell, rather than based on knowledge of the C-class.

Was the passenger window fully closed?

Has it got a sunroof?
Had this once with a blocked drain pipe from the channels around a sunroof
