  1. General
    Several months ago, a buzzing noise started directly related to speed. My Michelin tires were fairly old and I thought it might be a wear indicator. The buzzing sound increased over time into more of a rumble. My mechanic says its the front bearings which requires replacement of the ABS units...

    I have a 2003 trailblazer LTZ. Sometimes when I turn the car off, I hear a buzzing sound coming from the small speaker near the drivers head. I can't make it turn off. Does anyone know what that small speaker is for, and why it makes the noise?
