We finally found a button to press on the turn signal arm. It has the high beams symbol w letter A Had the same issue driving in dark in fog.The automatic high beams feature has caused us issues on two occasions (we have a 2020 Blazer). Once in a sudden snow storm and again in heavy fog. We live in upstate New York and neither situation required us to drive less than 25 mph. The high beams continually switched off / on when they should not have been on at all. How do you override this feature? I've read the owner's manual and researched online. Can't find anything (other than if you're driving 25 mph or under).
