Thanks for the response, marswill, but I believe mine is different. I have read about the HVAC sound on this forum and, and long with your description, I'm certain this is different.
The sound begins soon after starting the car and continues for as long as the car is running, then continues after I turn it off for about 10 seconds. It is not coming from the center console or dashboard area, but definitely forward, under the hood, near the internal combustion engine's exhaust manifold. I'm assuming there is something electronic there...some sort of control/switch. I called it a clicking but sometimes is sounds like a popping sound (like an electric arc). It is not a regular sound pattern, but rather is a random pattern of occurrence. In the video you watch here while the car is running, one might imagine that the odd sounds are bad video sound quality doing something to the video microphone, but all those weird clicks and pops are not bad video sound, it's the car.
