I continue to have water sloshing sound under driver seat area when vehicle accelerates and decelerates. I have located single drain plug under skid plate and evacuated a substantial amount of clear water. Sound still persists. Need advise on source....I suspect AC condensate drain as vehicle has been running AC a lot this summer. Vehicle is garaged and seldom exposed to rainfall. Cannot find AC drain hose to inspect/clear for possible clog. Need picture/schematic/video on location and access method.

Also eliminated sun roof drain line failure...found both on driver and passenger front windshield supports...both were intact and dry.
