How-To: Clearing Lexus GX470 AC Drain Line

Occasionally your air conditioning drain line can become clogged. This could happen because of dirt or in my case, due to a Mud Dauber that plugged it up. Without regular inspection, you may not know that it is clogged. One of the telltale signs is water dripping onto your passenger side floorboard. If you see this, chances are you need to clear your line.
