Check the voltage to the motor first if the fuses are ok. make sure the ignition and blower is turned on.

As above, check the basics first.

I've just fitted new brushes (£12.50 on eBay) to the blower motor in our 1996 / 120k mile Audi ... they are a 'consumable' item unfortunately.

are the brushes easy to replace ???

Yes, once you figure out how to get the motor out (through the glove box, on our Audi). I assume the blower motors are pretty generic, mine was a Valeo one.

Once you get the motor out of the housing the two brushes are just held with a spring clip each. Each brush has a length of copper braid attached which is soldered to a plate on the motor. Ideally you need a powerful soldering iron to get the old braid off and the new one connected, but failing that I think you could just cut the old braid and run a small self-tapping screw in to clamp the new braid against the plate. I'm sure that would work OK.

I did the whole job in about an hour, inculding blowing the innards of the motor clean with compressed air. Mrs BTB was well impressed!

A replacement motor was about £80 plus p&p on eBay, so £12.50 for the brushes was a result
