super cab water leak

as some of you know i am doing a quick resto on my 96. i have had a water leak for sometime and havent been able to pinpoint it . so i had someone run water over the cab for me last weekend to find,,, nothing. its been raining here all week and i have checked the truck every day to see if its wet. today is the 1st i noticed water. it was on the rear cab wall , under the slider, on a flange about 5 inches below the slider, it is right above where ford seam sealed the back wall . so its coming internally somewhere. i will take off the third lamp tomamrow and duct tape it off to verify thats not the issue, but any other ideas, i dont see any other water from the slider so i am doubting the sliding window seal. thanks

I'd say third brake light. At least it would be easy to rule out by hitting it with the hose and taking it off to check for moisture inside.

Either the 3rd brake light gasket(they tend to dry out and no longer seal)

Or the rear window gasket is not sealing anymore.

I would start with the 3rd brake light just because it is easier

Just a thought, take some kool-aid, mix it up in a spray bottle with water, and keep spraying both seals....Theoretically, if the seals are leaking, the colored water will show up, and you can find the leak faster...
