Was bedeutet der Fehlercode?

The signal from the blower fan knob is faulty. This is probably caused by a defective potentiometer, or by a short to supply voltage or ground in it. The control module then works from a midpoint value, so the fan may run at the wrong speed.

Mögliche Ursachen

Defective potentiometer
Potentiometer shorted to live voltage or ground

Was Sie tun können

1Check that the fan knob works by changing the speed of the cabin fan
2If the fault returns, have a workshop check the control and its connector
3If the fault is permanent the climate control module must be replaced, since the potentiometer cannot be replaced separately. Have a workshop do this
4If you have a diagnostic tool, activate the fan from the activation function and listen for it to start

Symptome, die Sie bemerken können2

The blower fan runs at just one setting
Buttons and control knobs on the centre console (climate) do not work, work reduced or work incorrectly

Was der Fehler beeinflussen kann1

The control module uses a value equal to half of the fan knob's maximum travel
