Hole in wheel arch or floor pan or sill or a split seam. Windshield leak or door seal leak. Drain holes in bottom of door blocked.
actually - the correct answer is, your heater core is leaking. if it's not raining & they're not driving thru water puddles, then "always" wouldn't apply. if the car isn't driven during rainy times & it's still wet, seals have nothing to do with it.
if you are unsure though if it's your heater core, you can find out easily enough by taking a section of heater hose & temporarily bypassing your heater core (disconnect both heater hoses, & connect a new single hose across both heater core connections on the engine). this will not affect the engine or hurt the car in any way (in fact, it's been a long time way of stopping a cooling system leak for many until they feel like tearing apart the inside of their car to replace the core - which is a quite a job in many cars). after replacing the hose, dry the floor with a hairdrier & see if the wetness returns. if not, you know it's the heater core.
I believe it is #42 in the floor board fuse panel on the passenger side

The reason for the problems with the horn on the Corvette could be attributed to a faulty fuse or horn relay. This can be located in the fuse and relay box that is located under a panel on the passenger side floor board.
under the passenger side floor next to body rail
Crack in the heater core
On the passenger floor in the toe area under the mat. Flip the two quick releases and there you go.
