Water On Car’s Backseat (Driver Side): Need Help Identifying The Issue

[rk.exe]

Hey everyone,
I'm having an issue with water accumulating on the backseat floor of my car (Tata Punch), on the driver’s side. I don’t have a sunroof, so it’s not leaking from there. I took it to a service center, and they said it was due to the door beading, which they replaced, but I’m still facing the same problem.
I attached a picture that shows a round hole, which on one side has a cover but is missing on the driver’s side (where the floor is wet). Does anyone know if this missing cover could be causing the leak, or if there’s something else I should check? Any ideas or advice would be appreciated!

One of the reasons can be a block in the A/c drain pipe.

The next time, run the AC for some time, and look under the vehicle behind the passenger side front tire. There should be water dripping onto the ground

If you don’t see water dripping onto the ground, then the reason may be that the evaporator condensate drain tube is plugged, and the water is running down the inside firewall, under the carpet into the back seat floor.

The drain tube can be cleared with compressed air.
