Cause

Correction
Replace the deadener following the procedure below.

Remove the door trim following SI.
Remove the water deflector.
The above illustration shows the deadener to be removed.
Do not twist the putty knife when removing the deadener.
The deadener can be collapsed by tapping on the center. After you have collapsed the center you can lay a putty knife under the deadener and pry it off the door. Refer to the illustration above. After the center has been removed, a mallet may be needed to tap on the putty knife to remove the outer perimeter of the deadener.
Remove most of the deadener until it is smooth. Refer to the illustration above.
Vacuum out the bottom of the door.
Apply the new deadener to the outer panel in the old location.
