Replacing the component

The fault has probably occurred as a result of a defective potentiometer or a short-circuit in the potentiometer. If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the control module or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. If the fault recurs, replace the control module.

If the fault persists, replace the climate control module (CCM). The potentiometer cannot be replaced as a separate part.
