Turn it up then get back there and start touching stuff until it stops...then you'll know what to fix.

It's probably the tan piece of plastic at the top of the back door.

Dynamat or another good constrained layer dampener is your friend.
Peel-N-Seal from Home Depot is not....don't skimp...buy a bulk pack of the good stuff. Do your back wall, the area under the rear seat and some in the doors. You'll know why it costs what it does after you get it finished.
Many people will tell you nowdays to go with 25% coverage but a bulk pack will let you really cover the problem areas.
