Turned on the defogger button this morning and the rear window and mirrors defrosted, but not the rear quarter windows. They look like they are wired for heat. The manual says nothing. Am I correct, or are the wires some sort of antenna?

I hope it doesn't get worse when I tint those windows

According to Repair Manual they are FM -antennas, 2 at left side, 1 at right side, the roof antenna is the fourth FM antenna and AM antenna.
