The noise is coming from the ACC Fan, it needs a little oil that's all. I found this solution on past bulletin boards, it took me 10-15 minutes to clean and lube my Acc Fan and it has been whisper quiet for 6 months now.
SOLUTION
The ACC sensor fan is located behind the 'bulls-eye' grill next to the right seat heater button. There is a small fan that draws air in through the 'bulls-eye' grill to a temperature sensor. This allows the ACC to accurately monitor the temperature in the vehicle. The fan can get dirty or dry of lubricant causing it to make a ticking noise.
The ACC sensor fan assembly can be accessed by removing the cover on the right of the center console, or some have reached it by removing the ACC unit itself. The ACC sensor fan assembly simply snaps in behind the 'bulls-eye' grill. There is a foam rubber gasket between the grill and the ACC fan assembly sensor to take up any play.
Carefully remove the ACC fan sensor assembly, unplugging the wire harness. Note which side of the assembly is in the top position. Keep track of the foam rubber gasket.
Using a paint brush or such, gently clean the fan. A can of compressed air like that used to clean computer keyboards or cameras works well.
Apply a couple drops of light oil to the fan shaft at the points where it contacts the supporting/bearing surfaces and at the very end of the shaft.
Re-assemble the ACC fan sensor assembly and re-intall. Don't forget the foam rubber gasket or the wiring harness. Some BB user's have reported better reults if the ACC fan sensor is re-installed upside down from the original position. I suppose this may help equalize the wear on the bearing/support points.
Turn the ignition to the on position and listen carefully to the fan. Make sure it moves freely and that the fan is no longer making any ticking noise.
Re-install the center console cover or ACC unit.
