Report: Water Leak and Sloshing Due to Clogged Evaporator Drain
Jeep Grand Cherokee Problem
Average Mileage: 167,333 mi (100,000 mi - 202,000 mi)
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.
Wet carpet on passenger side. Carpet was peeled away to reveal trouble spot, debris was removed and has been several times every 20k miles or so.

We noticed puddles of water on the floor on the passenger's side. The shop said the evaporator drain was plugged and fixed it.
