Cabin air drain
I was wondering if anyone would know the where abouts of the cabin air intake drain for my 2012 F350 diesel? My wife says there is a mold/mildew smell coming for the truck when I have the fan on. I started thinking that with the location of the cabin air intake at the bottom of the windshield and the pretty decent size gaps in the slotted intake cover, that I may have gotten a fair amount of pine needles and pollen down in the intake. That kind of accumulation over the past 13 years that there may be a blockage in the drain. Any information would be greatly appreciated. Especially pics or diagrams. Y'all have a great day!!!

My 2015 had that musty smell, and I ended up using a spray in the intake vents that was made for that purpose. Its been years, can't remember what it was called...... sorry.

This is the nipple that is your air box drain
pour water down the drain , from inside when you are finished , to flush the box and drain.
