Hi,
Now the winter is comming where I live in Northern Europe. What happen then? Of cousre the heater blower fan stopped working. I google on it and found that it is very common that the brushes are worn out. The blower doesn't cost very much and I ordered a new one direct. I normally use Mercedes parts which is much easier to find in Europe and much cheaper also.
I wrote it down with photos of my experiences from this blower replacement:

I hope it can be to some help for others who have the same problem with the heater blower.
