A few days ago the blend door was working properly, but now if I turn the knob to hot it clicks like it's stuck, but if I turn the knob to cold the clicking stops but it's still blowing hot air. Would it be possible that the blend door and the knob are out of sync somehow?? Because no matter where I turn the knob I always get hot air. Would there be a way to sync them together if that would be the problem?

On cars when I was growing up the blend door was moved by levers and wire or cable like bike gears.

Now it is electrical the knob is a switch and sends current to a motor. More then likely you need a new blend door motor
