Open the passenger door and look forward of the door hinges between the fender and the chassis. There's a stiff piece of foam in there that's sort of stuffed in place to absorb sound. See if that piece is moving around at all (and for comparison, check the driver's side for the same foam piece). I was chasing a similar sound on my '19 right after I got it, and in the end it turns out that foam piece was floating around behind the fender, and over bumps you'd get this odd sound that seemed like it was coming from the glove compartment. Had the foam replaced and it was quiet as a mouse.....
Added a pic of the foam piece when it was loose. That sliver of foam you can see towards the left should be fully stuffed in so you can't see forward. In my case it got "unfolded" and was flopping around....
