Hi, I have exactly this problem on an 04 Model, did changing the suggested component fix the problem.I have had a look down by my left hand leg and find a buncj of components down there, I found a device with an aluminium heat sink attachedv that projects into the fan airflow for cooling - is this it , It has two green electrical connection blocks. It is clearly not related to the control panel as with this removed from the car the fan still runs at full speed. rgds Adrian Covill
