The problem is the Hyundai Sonata NF collected at the TagAZ. Defective is that climate control is no more responsive to air quality. This function is answered by an AQS sensor that transmits a signal for closing or opening the lock.
The fault can be determined in the following way: when you click on a button (A) on a climate control with the air conditioning down, the flap will always be closed and the sensor will not react to the sensor when it is turned on.
The reason is that the wiring on the factory is wrong. Therefore, wiring the wires from the sensor does not match the pattern. A problem is being addressed by connecting the signal circuit of the sensor and the climate control-control unit according to the factory layout
