Well why didn't you say so in the first place. That's a very likely suspect. Thankfully you live in an area with little rain so probably something you can live with for a while.I think it may be from the rear sliders. I took all of them out a while back to check for rust. I removed the caulking behind all of them, as I was planning to put Explore Glazing replacements in.
But then I had to start driving this vehicle much sooner due to my accident in my 200 series. I just put the side windows back in with no caulk and used the trim pieces to hold them in place.
