Annoying Rattle 2001 T/A

[72Lemans4Door]

My 2001 Ram Air Trans Am has all the sudden started this extremely annoying squeak noise. It sounds like when two pieces of plastic rub against each other that are too right. It sounds like its coming from the drivers side mirror but I've taken it off and loosened it and tightened it but nothing is working. Someone please help!

Did you open the door panel and check for anything loose inside?
