Can anyone tell me what the technical name and purpose is for this little, black "nub" (that I circled in neon green) at the top, center-ish of the rear window (stock photo of 2008 Honda CR-V EX-L)?
I have the same vehicle, but that little "nub" is missing so I have a small, 1-cm (.40 inch) diameter hole where that piece goes and I need to know what it is so I can replace it or find a specific cover/hole-plug for it.

 

not sure, newer Hondas aren't my thing, but it looks like it is a windshield washer nozzle no?

 

It's the rear window washer nozzle.
