what are these?

I have a 97 Honda accord and on the outside of the driver's side and passenger side front windows, there are these two things. They look like window wiper nozzles without the holes. I am attempting to put deflectors on the windows, but these are in the way. Before I take them off, I would like to know if they are important. Any ideas?

Hey man Those are for your window It helps it keep it on the track.. If the window pops out that will help guide it back on track well i hope it helps dude
