Re: Buzzing noise near Climate Control System

The ACC sensor fan is located behind the 'bulls-eye' grill next to the right seat heater button. It is a small fan that draws air in through the 'bulls-eye' grill and across a temperature sensor. This allows the ACC to accurately monitor the temperature in the vehicle. The fan will run for awhile even after the ignition is turned off. 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 by using a thin, flat object like a credit card or puuty knife to remove the ACC unit. 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.
