To update my post. I found a mechanic who said it was the motor mounts. We replaced them and the sound went away for about a day. He then took my passenger door apart and test drove it. Put a hand on the speaker and the vibration stopped. It seems the speaker was broken. Not blown so you couldn't tell just by listening. We replaced the speaker and the problem was solved.

I have the same issue and wondering if anyone has resolved the problem. I get the same vibration behind the glove box. Only on ICE. It may go away for days or weeks and then come back louder than ever. Before I take it to a dealer and spend a lot of money I was hoping to have some idea what the cause could be. I have tried all the fixes mentioned so far and nothing really helps.
