Ticking Noise in Back Windshield

Hi -
My jeep seems to be making a ticking noise in the back windshield. I notice it when I’ve been driving it for a while or on hot days. Once it starts I’ll continue to hear it even though the car is turned off. Is it the glass? The seal around the windshield? How is something like this fixed.

After you stop, can you make the noise change by pushing anywhere on the glass or around the edge?

Do you have a rear wiper? If so, could the wiper motor be driving and wiper not moving?
