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 may be caused by interference at start up of the control module. Intermittent faults may also be caused by other types of intermittent faults. 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.
