The street side window over the couch rattles excessivley in our 2011 28Z Chateau. The dealer has put in a kit of window channel shims and now ordered another rubber gasket kit. Very annoying while driving. Any one with experience or fixes?
We had the very same issue with ours - I put a piece of weatherstrip foam tape inside the side channel where the window slides into the frame. Hasn't rattled since. Hope it works for you... I know that constant rattle can drive you nuts!
