I have a rattle type noise and vibration that can be felt through the car. worse when you turn A/C on and I have had two A/C compressors and it is still there. the first video is with A/C on and the second with it off. Toward wheel you can hear the light vibration the most.

Thanks for the videos it makes it much easier to get to the bottom of the problem without guess about the noise. The first thing I would do is remove the serpentine belt and then start the engine to see if the noise is gone. If so then I would lean toward the serpentine belt tension-er (if you could get a video of that with the engine running it would help as well) if the noise it still there I would look at the harmonic balancer or timing chain guides.

The video upload is a new feature I can see it helping us fix anything now.

Let me know what you find then I can send diagrams of the repair to get you back on the road.

Cheers, Ken
