From everything I have seen, the new Blazer doesn't have a Start Stop disable button. Some GM vehicles do, some don't. There are aftermarket companies that make Start Stop modules that plug in to disable the start stop system. Has anyone had any experience with the module yet?
Unfortunately, the Blazer does not have a disable feature/button. Some people have said, you could put it sport mode and it will disable the start/stop. So far, that is not true. I will continue to try and find a way. No, I haven't tried a module.
