Intermittent Vibration Noise In JSW Passenger Door

On certain road surfaces the passenger door behind the driver makes an intermittent buzzing vibration noise. If I press my hand hard on the surface sort of near the door handle, it briefly subsides.

How do I remove the door panel? I see a single bolt at the very bottom of the door panel, but don't want to assume that this is all there is to it.

Thanks y'all.

you may have to pull the trim cover that goes under the armrest... may have some bolts there too.

I have the same issue with my front passenger door. It comes from the Speaker area though. Good thing I'm removing it tomorrow for trim wrapping.

Thank you Steve. I'll check for fasteners under the armrest too.
