Just keep the AC on and it never shuts down...Oh I live in Florida LOL!!!I hated it too but then you get used to it. I think the only time I get annoyed with it now is when it goes off too quickly when you stop and then the light turns or the person in front goes so the car has to kick in again. I do agree that Chevy should make it an option to turn off on every vehicle and in this day and age where cars update their software OTA I am not sure why they cannot provide an update that would allow the disabling of auto-stop on the 2019 blazer.
In the end it does help save gas mileage though.
