I have a 2015 Veloster Turbo. This morning the Climate control knob was working fine. This evening not so much. Number 1 doesn’t work, #2,3,4 will work kind of. I have to turn the knob slightly just before the number for it to turn on, if it’s on the number nothing. Is this a control knob issue, or a blower resistor issue. If it’s a knob issue where can I get a replacement outside Hyundai, or does anyone have a hack to fix it until I can replace it. I live in Ohio, and Mother Nature decided she wants to bring in the cold weather.
