Hum/buzzing noise while climate control is on?

[boggle]

My pro acts exactly the same. Cycling the ac off/on again and the hum vanishes, climate control works perfectly. I can’t imagine that this is a sign of health. Did you ever investigate, or take it to the dealer?

Never investigated further, but definitely still happening. Hard to replicate but seems widespread, hard to replicate on demand so figure dealer would just give me the runaround. Wonder if @Ford Motor Company has acknowledge anything by this point. Might try texting the video of the video to one of the Lightning support lines and see what they have to say, they've been surprisingly receptive.
