Automobile air outlet knob is an important part used to adjust the direction of air outlet. If the aluminum alloy knob is replaced, the shape and size of the knob will be changed, which will lead to the mismatch between the knob and the originally designed air outlet, and the direction of the air outlet will also be affected.
In addition, when replacing the knob, pay attention to the installation position and direction of the knob, so as to avoid improper installation of the knob, which may lead to abnormal adjustment of the air outlet or other adverse consequences.
