Clicks coming from left and right side of dash

[CommandoFL]

I get a a click noise from the left and right side of the dash when then the ventilation system is on. It's not constant, just a click....5-10 seconds passes, then another. This can continue on for a few minutes then go away. It just seems to be so random. Any ideas.

I hear something similar in my 3, only when the AC is running. I recorded the video and had my local service center check it out. They tightened a bunch of bolts in that area but it didn't fix the issue. I'm curious if this is the same thing.

I had a clicking sound from my AC system a while back, but only when i would turn it on OR when i would split the airflow from one stream into two. Turned out that some vents were loose, so they tightened them and the noise went away.
