[quattro4]

Solved - Would love a little guidance before I tear into things as I'm still learning these cars.

Constant buzzing coming from behind the dash with the ignition on. seems to be loudest behind the HVAC controls.
1) Pulled the radio - cant see anything there.
2) Pulled the clock - sound seems loudest towards center.
3) Under the hood - much quieter and still sounds central.
4) Opened the smugglers box - not coming from there.
5) with doors and hood closed - not really audible outside the car.
6) no chance with AC fan or dash fan activated - meaning buzz still faintly audible when they are running and no chance with fan speed.

Thoughts on what I should be looking at for likely suspects. Hardest area under the dash to get a look at with the center console and AC.

have a video but not sure how to load those.

TIA
