So the part that is highlighted in red broke on one of my rear windows today. I googled a bit, and tried autopartswarehouse.com and a few other site to no avail trying to find this part.

Could someone please tell me what this part is?

I'm sure I can track one down once I know what exactly that part, or assembly is, but does anyone know offhand where to get this part?

 

You cannot buy it seperate. Just order a new latch assy from the dealer, they are cheap and the correct color.
