Issue Description: In JL/JT vehicles, many dealers and customers are not fully aware of the correct way to install the Mopar all-weather floor mats, especially the front mats. The all-weather mats are installed without removing the slit/perforation portion of the front carpet, which blocks the drain port on the all-weather mats completely and does not allow water/any liquid to get drained out of the vehicle through the drain hole on the underbody floor. Correct Installation Method for Mopar All-Weather Floor Mats 1. Find the slit/perforation on the front carpet (near the outboard mat post on the carpet )and cutout that piece from carpet. 2. Remove Drain Plug on the drain hole on the underbody floor 3. Install the All-Weather Mat. Make sure the mats built-in drain port lines up correctly into the drain hole on the floor. 4. Insert the drain plug in the drain port on all-weather mat to close the drain port. The plug is to be removed whenever there is need to drain water on the mat or to wash out dirt without removing the mat form the vehicle.
