Water Leak and Sloshing Due to Clogged Evaporator Drain on Jeep Grand Cherokee

Problem Description and Possible Solution

The AC evaporator drain commonly clogs and causes water to leak onto the passenger side floor. A sloshing noise may also be heard from the water inside the heater housing. Decaying organic debris in the housing may cause an odor. A service bulletin (TSB 24-06-96) was released; it describes how to clean the drain tube without removing the heater AC housing.

My passenger side floor is always wet from running the AC. It seems to be coming in from the outside of the floor, as water always drips in that location. I can not see anything leaking on the inside of the jeep and the spot that is always wet is in the middle of the floor or towards the front of the passenger side seat!
Driver side floor mat (carpeted) and underlying carpet sopping wet. No rain in the previous 48 hours. Has been hot so A/C being used. The fluid is odorless and feels like H2O so I am assuming it is a water leak. What is different for me is that these posts almost always point to passenger side. I am dealing with a wet DRIVER side FRONT floor carpet and floor mat. Any suggestions? I am planning to take it in to have AC evaporator drain checked as well as sunroof drains. No warning lights so I feel 100% confident in driving it.

Will appreciate any guidance. Thank you!
HVAC drain hose is misaligned and drain inside the cab, dealer found several gallons of water in compartment under driver seat and wet carpet. Dealer want about $700 to fix and certified warranty is denied claim
Found an Internet website with instructions to install a hose on the end of the ac drain tube. Problem is that the original tube does not aim down enough so the water drips from the inside of the tube and backwards along the tube underside back into the the interior because the the gasket for the tube at the firewall deteriorates. Have to cut into wheel well to find the tube. No access from anywhere it is in a hidden crevice. Once we attached a piece oh hose aimed down with a hose clamp problem resolved.

Sloshing inside passenger dash while air is on; passenger front and rear floorboards 1-2 inches of water. Looking to fix it myself still...under my hood is different from 1:08 youtube video on how to clean it out.
Sound of sloshing and leaking from evaporator tube. As a result the carpet area on passenger side is soaked.
