06 F-250 with a sunroof. It has been raining here for about 4 days straight. I noticed that my headliner was wet around all four doors of my truck and sunroof. What may be causing this and is it possible to save my headliner from mildew and water stains?

 

There is a drain in the sunroof. Push the sun screen back and open the window, then use some air to blow it down, that should open the drain.

Post #19 shows the sunroof water drains or channels.
