Thanks for the opinions.

Arthur: Though I did not suspect the tensioner damper, I didn't find any reason not to check it again, so I tried the famous O-ring fix. Result? Nothing. The noise is still there...

MrCjames: I'm not sure I understand your idea. If I hear the noise when the climate control is shutted down with the "0" button, then can I rule out the idea?

ScotzBenz: The shift lever is very solidly fitted. I tried to grab the shift lever when the noise came, but there was no unordinary vibration on the lever. I wish I can fix it with 85 cents like you did...

buckwheat: Yes, I will post the solution once I find the source.

One more information on the noise: The noise is a kind of FADE-IN (gradually louder) sound. That means there is a resonance I guess.
