check if you can here the fan running. If not the cause can be that the bushes have reached there limit and need to be replaced. If you have the time and tools, you can remove the motor and get to the bushes. You will find that they have been worn down to a curn shape. If you remove each bush, and flip it 180 degrees, then the tip of the bush will make contact with the motor shaft. This will give you many months of fan life and save you a packet. You could also replace the buses with new ones - Audi do not sell them but can be matched by good auto shops.

Hi, first off, check to see if there is anything else on the same circuit, e.g is everything else working with the fuse blown. The cigarette lighter is a favorite. If everything else is ok, use a a multimeter set to amps from the positive battery terminal to the heater motor input terminal (with a suitable fuse in line) to test the amps draw of the motor. You can then compare this with the fuse rating recommended and if it's greater than 2/3 of the fuse rating, then replace the motor. e.g 10 amp fuse 7 amps max loading, 15 amp fuse 10 amp loading.
Hope that helps Matt..
