Blend door?
So I have a 2013 ford Taurus, I've noticed the passenger side the AC is coming out cold and the driver's side is kind of warm. I haven't checked the freon level, but I read that the blend door could be messed up.It's a dual zone AC is there a way to diagnose the blend door I'm gonna throw some gages on it today. After work but if the freon levels are good.I'm just trying to find a way to diagnose that thank you for the help
