Driver side floor leak after rain or car wash on 2008 Lincoln MKX

How do I troubleshoot a leak to the floorboard, driver side after a rain or car wash? This car is garaged so I know it's only after a rain or long car wash. Tips appreciated. Regards.

Do I need to remove the plastic cover over the windshield wipers? Or, just use a car wash wand and spray directly into the grill. I tried to find the location to clean but was unsuccessful. Thanks.
