What's this annoying buzz of the heating sys?!

akraptor · 03-18-2009, 08:03 PM

Even if I have one line on the dash. . .the system is buzzing like it delivers some mega-heat. Why is this noisy? And the sound goes up and down continuously (beefing up/cooling down) like I am on nuke power generator. .

Instead of hearing just a woosh. .going up in volume as I turn up the heat volume. . .I hear this buzzing. .which is getting annoying after a while.

Maybe it's just your car... you should probably get it checked out if it bothers you that much

akraptor · 03-24-2009, 09:01 PM

It doesn't bother me that much. . .when I turn the music on.

Try to locate the vibration of the buzz by using a stethoscope.

Really?! your heating system is noiseless?! I mean the noise is not like something is wrong, it sounds like a normal sound, but didn't expect it. .

No strange noises here

Huh, it's not strange. .it sounds like a tiny power generator. .hums up and down like it has an engine variator. revving up and down. Damn, I'll ask the dealer. . Wouldn't be surprised he has no clue. Then, I'll ask a mechanic. Strange, if I pump up the air flow, the buzz doesn't follow up. It stays at same volume.

Have you considered that this noise might actually come from something else?

I assume you have the navigation DVD in the DVD drive?
And/or a CD in the CD drive?

If so, try to eject them and see if that is the source of the hum noise. CDs or DVDs can create this noise when they are slightly out of balance and/or warped. These drives (especially the DVD drive) constantly rev up and down when the navigation computer tries to access the disc or when you are playing music from a CD.

Not from something else. I don't listen to music most of the time. When the heating is at 1 or 2 I can hear the buzz, whizz, or whatever you can call it. When the heating it's at 3-5 is not audible because the woosh of the air covers it. When ventilation is off, no buzz.
