Windshield Noise
I have been having a "whistling" noise emanating from the upper left side of my windshield, also. First trip back to dealer verified it was the windshield header seal. When I picked it up after replacement, it was still making the whistling noise. Yesterday, I put some 3M Residue-Free Duct Tape around the driver's side of the windshield just from the windshield glass to the metal of the windshield. The whistling noise was gone. I took my JLUR back to the dealer today and they are going to create a STAR case and, they thought, FCA would replace the windshield and seal. I looked at new JLs on their parking lot and the seal is laying down against the paint. Mine used to but now has a gap where the seal meets the paint.
