Water Coming in the Cab via "Oh Shite Handle"

We've had some decent rains recently, nothing to write home about, and I've got water coming in through the A post handle on the drivers side. I haven't done anything to the truck that would be above the handle since January, and that was mounting my light bar (fire department) via the roof rack pre-tapped holes. I've had a fair amount of windshield noise and am wondering if it's coming in the top of the windshield after shedding off the roof.

Anyone else have this?

 

If your under warranty, let the dealership handle it, if not, remove the A-pillar handle and that whole plastic piece pops off so you can see where the water is coming in from.

 

Just sounds like a faulty seal. Bring it in.
