When the rear window heater is not working in a Toyota Aygo the first thing that I suggest that You do is check the fuse to the heater assembly. If this has blown then the system will not get power and therefore it will not be able to turn on and work. Another thing that You can check are the actual wires and traces that are in the glass here. If any of them are broken or damaged then it will fail to heat up the glass as well. In order to repair that You will usually need to replace the entire rear piece of glass to restore continuity through a new sheet of glass.

I’m not sure, but you might check to see if your car has a bad/burnt out fuse.

If your Toyota Aygo rear window is not working it's usually a problem with the window motor or regulator.
