Whirring/Clicking Sound at Dashboard Left Side Area

There's been an on-off whirring/clicking sound around the left-hand side area of the dashboard; and I have been left wondering where exactly is it coming from. I found out today that when the sound comes about, it would immediately stop if I turn the aircond off. So now I know that it has something to do with the aircond.

Searched online across Toyota Harrier/Lexus RX discussion boards and found that it was a common problem across the make. Note that this affects both the 1st and 2nd generation Toyota Harrier/Lexus RX. Seems that there are 3 servo motors that control the aircond and these may make noises after years of usage- a replacement of the aging motor would solve the whirring/clicking sounds for another few years of usage. Cost of replacement was mentioned at app RM300.

There you have it, folks! If you have the same whirring/clicking sounds around the left-hand side of the dashboard, you know what is affected when you are seeking your mechanic's opinions.

Or you could do what some other forumers practised, which was to increase the sound system's volume :)
