Morning all! I just had a window issue with my Model Y and had some tech support over the phone. Whist fixing the issue they asked me to check on something to see it if was enabled ‘Enable Rear Defrost’. On my car it was not. The service tech told me a lot of new MYs left the factory with this disabled and told me to enable it. There have been a number of threads regarding the rear defrost so this might be the answer.
To get into service mode: Click on Software, then hold down your finger on the Model Y logo. Let go and then enter ‘service’ as the password. Then click on ‘Closures - Windows’ and you will see the enable rear defrost icon. If it has a green outline it’s enabled, if not click on it to activate.
