So on my mini I have the 3 different controls for my air conditioning and AC. There is temperature, then fan speed, then where the air comes out (up, down defrost etc) I was wondering if there is suppose to be a light behind the 3rd control **** (the one that controls where the air comes out) Mine has lights behind the other 2, and it annoyingly doesnt have a 3rd one. If this light is just out does anyone know how replace it??
