(Updated June 13, 2019....Noise source found. It was the DASH CAM!)

I was driving along today when this weird noise started. It's happened before a time or two for just maybe 10 to 15 seconds here and there, but this time it kept doing it.

Pay no attention to the camera orientation; I was trying to record the noise before it went away and wasn't concerned with the camera view. After I disconnected the battery, the sound stopped. Possibly from the aftermarket Sony radio? Could the climate control be making such noises? Could it be from the hvac fan motor? (ac and blower motor were working fine). Very bizarre. I called Crutchfield to ask if it could be from the radio. He said it sounded like a cd skipping or stuck in the player but there's no cd in there.

You should be able to watch this via this link which will only be available for a few weeks (link now edited)......
