Water in Floor Board - Land Rover LR3 Fix - AC Drain Plug not Sunroof

Land Rover simple fix for LR3 AC Drain Plug. After troubleshooting the sunroof drain that is a common issue, the window cowl between the hood and the window, I moved on to the drain plug for the AC. All three are easy to access for the most part but the AC drain plug is by far the simplest to investigate first.
