    Hello, guys
    My lovely one has problem with this noise and I have no idea how to fix it. it comes from around mid of dashboard through passenger side (not sure). on that day, it just happened when my gf started an engine, and when car moving.

    The only thing off the top of my head, would be a nut, acorn, etc down in your blower motor housing for the heater. Sometimes it happens when the filter is changed or a critter gets in there and chews it up. When the blower runs, the fins beat the acorn. Does the pitch change with speed changes in the blower? Do I see the clock flashing when it happens? What else happens? Have you changed the cabin air filter recently?

    I don' think my '04 has one of these, but it sure sounds like a geiger counter to me.

    The pitch didn't change when speed changing, but I didnt look at the blower. air filter was replaced 6 months ago. and my car has problem with the dashboard. that doesn't work sometime. I mean it has nothing show up when start a car.

    The combination meters go bad in these cars, but I think it would be a stretch to blame that right away, although there is a case for it. I'm going to try to open that video of yours on a computer later to see if the noise is any more identifiable

    That whole deal looks like it is in need of a few good grounds. Does the monitor ever have moving lines on it when the car is running?

    If you are sure the sound is coming from the dashboard, passenger side, then the sound is likely caused by the cabin ventilation fan (try turning off the fan when the sound starts).

    Ok so. The blower isn't the issue and you have dash lights out? Just illumination, or does your instrument cluster stop working as well? (Speedo, combination meter) how about your MFD/hybrid system monitor? Please list all the symptoms and when they occur.
