Maybe one of the stops at the top is loose. When the window is rolled up the pressure on it would keep it from rattling.
The door panel will obviously need to come off to fix any problem in there, so you'll need to start by doing that first. Then check the two stops at the top of the door. There will be a nut on each one you can easily tighten/check.
