Water leak front passenger side

[JRW]

My 2000 ML320 is experiencing a wet front passenger side carpet. Drain
holes under the door sill are clear. All visible debris was cleaned
away from the front windshield catch, run-off tray, yet water still
makes its way to the floor. You cannot see any interior dripping.

Any insight or help is appreciated.

Pretty hard to diagnose not being able to see it but perhaps you have a sunroof leak or your windshield seal is leaking.

You might want to check in with the W163 Forum for more specific advice. Good Luck!

Maybe is a leaking heater radiator
