Nasser footroom driver’s side on center console

Hello together, have for some time the problem, that with me especially with rain, snow and cold, the inside of ALL windows so extremely fogged, that it can hardly be fixed. Now I have just noticed that the footroom in the area of the center console is wet at the driver side (wet) and smells of coolant and also seems rather greasy (Glysanthin??). What do, has jmd. an idea and possibly a instruction? Am grateful for any help, because no idea if the time critical is t?!?! Greetings PS: Have NO climate..
