battery drain issue, unknown heat spot

What's causing the heat spots above the rear window? The battery goes flat in 3-4 days when car is parked. I already unplugged 40A rear window defroster fuse for overnight but made no difference. It must be drawing a lot of power to keep the area clear like that.
