Leak in Pinch Weld under Rear Window

[DBarfield]

Hi guys, I thought that I had the sliding rear window leak posted here in the past. After water hose testing the back glass, I found that it was leaking into the cab from the right rear lower corner away from the slider drain. As a last chance before removing and replacing the rear glass, I RTV'd between the frame Window and saw that the leak was coming from the pinch weld seam below the window. Since it is leaking behind other metal in the cab, it will be hard to apply seam sealer inside the cab well. Any other thoughts? Any thoughts would be appreciated.

Are you sure it's not coming from the 3rd brake light? I'm in the window business and any sealer must be applied to the exterior in order to stop the water from getting inside in the first place. Once it's inside it's too late.
