Help identifying part

[tekfire07]

I need help identifying this black circular item to the right of the license plate light. This Tahoe is new to me. I want to make sure nothing is missing.
Thanks in advance for any help.

That's the secret button for the back glass. You can find those relatively cheap and are easy to replace.

Dang it....for once I knew the answer to something!!!!!!!!! Seriously, not a hard job to replace-mine looked like that one when I got my Tahoe!
