Mechanical buzzing sound

So, i am hearing a mechanical buzzing sound by the driver side (interior). Somewhere around the steering wheel or gauges. Anybody know what it is or experienced this issue before? It is random and lasts about a second or 2. Anything is helpful. 2015 tacoma.

 

When does it happen, when you 1st start it, driving along at any speed, ect..?

 

Driving along at any speed

 

MT or AT?

 

Is your cabin fan on? Could be a leaf by the blower motor?

 

I have this problem on my 08, sounds like its coming from the far left air vent. Will kick on and off randomly, or when I hit a decent pot hole. Cannot find any rhyme or reason to it, will make the buzzing sound with a/c on or off, cabin fan on or off. I'll tune it out most of the time but if it gets annoying I just turn the music up.

Edit: Mine will last longer than just a couple seconds. Will last from start-up to shut-down sometimes
