I'm new here, and I've been driving a 94 A8 4.2 for a few days. The car should actually be just a "winter car", but it is so much fun driving that it will probably stay a little longer.

But there's a catch. The fan of the heater always starts to squeak and whistle. It sucks !!!! A new air costs 316 euros at Audi. Who can tell me how elaborate the installation is???
If you want to do the work yourself, you don't have any experience at Audi.
I'd be very grateful for a few tips.
