New vents were installed, but I did have to remove my back seats.
It appears the pass side was leaking, but ever so slightly.
Just a little bit of dampness.
No wet carpets would fill the storage compartment on the pass side with a small amount of water.
My truck sets most of the winter, very little use, and sweat appears on the windshield.
I suspect the small amount of moisture from the small leak condensed on the cold glass.
I will keep wiping it down, and it should eventually disappear.
I will monitor it.
I have replaced my rear center high mount stop lamp (CMHSL), cab lamps (new OE units), and these pressure vents.
OK, any other areas for water leaks? Any improved parts, I'm just buying. I hate water leaks.
Moisture is a no-no in vehicles with body computers and networking; lots of weird things can happen.
Thanks, everyone, for the help, AK Bob, Mortifa dude, and igotacummins for the forum to help me fix my truck.
