Just returned from Ford service, I wanted them to look into the rear sliding window rattle, but of course with the technician sitting next to me, I could not duplicate the rattle even driving over the bumpy stretch of road that caused it to rattle several times before.

The tech thinks it might have something to do with the frigid low temparatures, this thought may be valid because yesterday the weather was above freezing and I did not notice any rattle..and today the weather was the same.......even the ride did not seem as bad as before..........go figure
