Automatic heating of rear window doesn't work

[YaR]

Automatic heating of rear window doesn't work when the options are set to enable it and you turn the AC on. It works fine when you press the rear demister button. Anyone else have this issue?

Automatic works when you press the front demist button. It is not linked with turning on AC.
