Ive searched through the net and cannot find a definative answer.

I have dual climate.

If i use the front window demist button the blower is very strong.
If is set the auto button the blower is strong.

If i use the fan speed control in the centre it starts slow on the first selection and increases in increments gradually upto about the third level then stays at this speed all the way round to the maximum setting, this is not nearly as strong as when on demist etc....

Could this be the Final Stage Resistor (Hedgehog) even if it works fully on demist etc?

 

In the menu, select the climate control and find the setting to reduce/increase the fan speed for the auto functionality.

 

Looked at this and it was already on the max setting, whilst driving along today i noticed the fan went up to max for a while then back down again (in manual mode) it works fine in all other modes?
