My heater blower won't work on positions 1-2-3 any more and 4 is a bit noisy to be using all the time, so does anyone have any idea what the problem is?

I don't suppose it could be something as simple as a fuse? I see from the handbook that the blower has two fuses, but of course the diagrams in the manual are totally different to the fuse layout in the car.

I saw something in another VW forum about a resistor - if that's the problem would a mechanically clueless person like myself be able to replace it?

BTW, someone raised the identical problem a good while ago, but there were no replies:
