Top 5 lines of Defroster have failed or are they fake? :)

is that normal behavior? i figure it may be the case since it's actually not visible from the rear view mirror but just want to make sure.

center section is from the heat coming from the rear dashcam... not strong enough to defrost much more than that small area.

Pretty sure it is failed but can’t confirm

The FM radio antenna is built into the rear glass and looks exactly like the defroster grid elements. I'm pretty sure that's what you're seeing.
