My guess is...
...that you have a loose wiring connection at the lighting wiring for the fan. The fan obviously vibrates when it runs, so it could be that one of the wires feeding the light in the ceiling combo unit has a loose connection. My guess is that the ceiling light and wall light share the same neutral, so I would suspect the neutral wiring connection being loose either at the fan or at one of the wall switches. But, I'm only an electrician by adjacency to the real electricians on my jobsites, so be careful taking any advice from me!

Are the fan and light controlled by the same wall switch?
