Hi all,

My S70 has ECC.

I've noticed that there is a rapid clicking sound from the center to right side of the dash.

Adjusting the air direction (middle dial) doesn't have any effect on the noise. I can hear the damper motors working and the air flow changes as indicated.

However, if I raise the R temperature dial a notch or two the sound stops.

The AC blows cold, there are no error signals from the control unit and the main temperature sensor is clean.

Also, the noise continues with the engine off as long as the ignition switch is on.

What's up?

Thanks,
Bryan
