If the vehicles listed above suffer from complaints relating to fan power or fan louver control, the following should be noted:
If the temperature control is set to the minimum or maximum, the position of the circulating air louver changes. This can make it sound like the fan power is changing.
However, this is a normal function of the climate control system. The symptom does not occur if a temperature is chosen between the two settings (Min./Max.).
