Help finding water leak...

[Ramintime]

My 2020 1500 has a water leak that I cant solve. Headliner is completely dry but water is a fast drip at above the rear window - middle and off to the sides of the sliding window, as well as the upper corners (photos attached).
Here's where things get weird...bought new third brake light, and sealed it with silicone. Also sealed the complete top outside of the back window as well as down the sides. Also sealed the shark fin antenna completely. The water still comes in at the same spots. What am I missing? Thanks!

Triple check your silicon sealing jobs and make sure theres not a gap somewhere, may have to use a second set of hands and use either a light or small amount of air to find the gap.

Panorama roof?

Most likely your rear glass frame is broken. And you can’t see the crack from where you stand. I have just gone thru this. With the exact same signs of water that you have: top of the window, corners, dripping out where the seatbelts mount to frame. I had the rear glass replaced three days ago with a single piece glass. It is raining now in SoCal and I’ve been driving around in that rain. No leaks. No leaks from glass, and none from center high brake lamp. None from shark fin. I’m dry!

Forgot to mention: I did suspect the center high brake lamp. Also suspected the shark fin. Wanted to narrow it down though before dropping the headliner. So before riding in the test rain, I masked the shark and the brake lamp with painter’s tape. Once I confirmed no water coming in from the shark fin I removed that tape and went back out for the brake lamp. Extensive riding in pouring rain and no leaks from brake lamp, either. It was the glass all along!!

You mean where the top of the sliding window is at? There's got to be a way to seal that from the outside...
