I went to the dealer here in Albuquerque today to get my left tailight replaced, while I was there I asked them to take a look at the squeaky driver window. When I went to pick it up they said they could not duplicate the squeak so I got in and took off, sure enough squeak, squeak so turned around and went back and told my service guy. He took a look at it and determined that it was the rubber behind the speaker, so he took it back and had them put a little bit of silicon sure enough that did the trick, mention this or try this next time you get a squeak. Problem solved until next time.
