I have the rattle from the drivers side door handle.
I took it to the dealer this week for that and about 6 other things.
They said they can't do any kind of repair on the door handle.
soooooo.........more or less tough sh*t !!
Tough sh*t on the spoiler that's loose.....AND
Tough sh*t on the outside door handles that are loose......
I guess it doesn't pay to take it in for more then a few things.

I'll wait a while and take it to another dealer, or maybe try this.....

Maybe this will help - Disassembling the door trim: http://www.swaaggs.com/documents/door_trim.pdf

 

I have that, too. I think its being caused by the o/r h pipe. (Harmonics)

 

No rattles or squeaks here.

I have a rattle in the plate right around the window switches on the driver's side door. Anybody know how to remove it? I'll just stuff some cotton ***** in there to tighten it up and absorb the rattle [&:]

 

remove the loose change and the buzz will go away
Lots of forum members have the dreaded loose
outer door handle. And the subs in the doors (??)

Regarding the door panel removing instructions, my suggestion is to go here:
http://www.crutchfield.com/App/Produ...mp;i=700MASTER

I got new speakers for my 05 GT, and it comes with this master sheet that has a multi-page document with detailed instructions and clear photos on how to remove the panels, since i had to remove them to install the speakers. The master sheet is free with speaker purchase, or, you can buy it separately for only $5. Also included is the document is pictured instructions for installing rear deck speakers and the head unit, so it shows you how to take all of those components apart. Good stuff. I came across this forum because like many, i bought these new speakers because i thought my driver side door speaker was blown. Only after installing the new speaker did i realize it wasn't them at all. I wanted upgraded speakers anyways so it was no big deal. Anyway, this sheet is great if you plan to get into any of these areas on your 05+ mustang. Enjoy...

 

Rattle behind the handle on both sides of the car. Its almosta "jingle" vs a rattle. Annoys me, but there are bigger things to worry about in life.
