Wet floor driver side

Hello everyone, I need help! The floor of the driver side of my car is always wet. What could be the problem? My car is an altis 2008. Thank you to those who can help.

Climate change, I’m afraid. We can expect more of this in future.

Is it definitely water? Are you sure it isn’t something obvious like the window leaking when it rains or condensation dripping from your aircon?

Check the connections/tubing for the windscreen washers, as @finley say’s drainage from your aircon, also corrosion under the windscreen, these are just starting points. You need to get down and look around see if you can trace it back.

The window on the driver’s side is open?

I’ve actually done this multiple times. After about the sixth occasion I stopped wondering why my floor is wet.
