I have a Honda Accord and the passenger side always stays sync with the drivers side, we never use separate temperature settings, my wife just turns the vent towards me and I’m even more happy. She had a a gmc Yukon that the climate control messed up and after removing the the dash, which was never the same, and over a $1000 dollars it was back working. Service guy said don’t be surprised if it happens again. So my question is why would someone opt for something complicated and a lot of things could go wrong when all you have to do is close or change the position of a simple vent. Are we just that lazy and spoiled?
