They sound like they are the rain guards, probably by Weathertech. (Unlikely to be the optional JDM ones, they cost a fortune.) Start just ahead of the mirros and end just behind the rear door top?
Unless they are cracked and nasty, I'd seriously reconsider taking them off - I paid $125 for my set and they help in a few ways; the windows have no frame, so when snow covers the top of the glass it will fall straight onto your seat when the door gets opened. The guard stops this.
In wet weather, it lets you crack the window an inch or two, without the rain from the windshield coming around the A pillar and onto your leg.
In hot weather it lets you exhaust air out the windows without so much wind turbulence.
When I park in the sun, I can leave all the windows down two inches, and nobody notices.
....but you can easily pull 'em off if you like - choose a warm day or use a heat gun to soften the glue so it doesn't pull chunks of paint off, then clean up with WD40 or similar.
Except now, every time the water spins off that A pillar onto your lap, you'll remember this, and curse me!
