Thanks for the comments. I switched off the aircon automatic mode as well as the auto mode that regulates the air circulation. Unfortunately I still get the short whirr sounds off and on, as if the computer is making adjustments. I guess one way is to turn the music up in the car. That way I don't hear the little noises at all....haha...

It could be the climate control. I could turn that off and just use manual settings. But if it really is the climate control, is it normal to hear the short whirring noise?

Hi everyone, I am driving an IS250 2009 model. From time to time I hear a short "whirring" noise from beneath the dashboard. It sounds like the on-board computer adjusting something. It's not loud or anything and it does not happen all the time but once you hear it, it does get irritating after a while. I was wondering whether the sound is from the automatic mode of the aircon adjusting the vents? It seems to happen only when brakes are applied. Pls advise if anyone has encountered this. Thanks.
