Humming after shutoff

[cappy]

After I shutdown the engine in my 1990 535 auto there is this humming sound that seems to come from somewhere behind the dash towards the middle. It pulsates somewhat.

anyone have any ideas?

I had the same newby question sooo... it is the vents repositioning themselves and is normal.

It takes about a minute or so for the flux capacitor to leak-down...

Whenever we have a problem with a new design, I blame the flux capacitor.

I'm told that when ever the AC turns off, a "fresh air door" opens. Mine is evidently broken, because when I smoke in the car with the window cracked, the smoke comes back in. Was quoted $180 parts and 86 labor to repair.
