Anyone else noticed / have a fix for a slight vibrating or humming noise directly to the left of the drivers seat?

I noticed this a couple weeks back, it's a slight rhythmic vibrating noise - at first I thought it was the speaker but I have been dissuaded of that. Best I can tell it is the door vibrating against the plastic directly below and to the left of the steering wheel. If I stick my finger in between it seems to stop... has anyone else experienced this? I have been thinking of trying to stick something there to silence it.

Thanks!

 

I haven't seen that but on my 2014 the drivers side window glass slaps against the rubber moulding on the highway with the window down a couple inches....most annoying.....

 

I can imagine! It isn't a big deal but I would love to silence it haha.
