Rear Window Rattle When Closed

[Cynthia Grant]

I know this has been addressed on this site, but I can't find the thread now. When my rear window is closed, it makes a "clunk" sound when the truck leans or goes over a bump at an angle. Sounds as if the glass is actually shifting. No sound when window is vented or fully open. I had my local dealer do the TSB for the rear window, but that did not help at all. They want me to bring it back again for them to figure it out, but I was hoping to get some suggested fixes from someone who has had the same problem (dealer seems to have no idea how to fix it).



PS: This is not a tailgate or tonneau cover noise. I've already checked those possibilities.



Thanks!

I would try to reset it. Maybe it is set to low and the "UP" pressure is not quite enough.



To reset it you raise and lower it 5 times. When your raising, you must TURN AND HOLD the button to the right during the entire time the window is moving up.
