seat heater buzzing question

["Berger, Anthony E." <BergerAE@ems.com>]

Hello again everyone.

Spent about 5 hours replacing my seat heater last Sunday and now I have a
tostie butt.  Two nights ago while driving home I started hearing a buzzing
from under (inside) the dash.  Starting checking stuff and found out that it
only buzzed when I had the drivers side seat heater on.  Any idea what this
might be?  Relay for the seat heater or something?  The seat still heats
just fine but I am going deaf turning up the radio to cover the sound
(actually I have been just driving with a cold butt).  Don't got my Bentley
yet so I don't even know where to start.

Any BTDT?

Thanks as always, there isn't a chance in H*** that I could keep my Audi's
on the road without this sites help!
