Water leakikng in? Back headliner wet

[89PBR96]

Anyone no where this leak would be coming from I removed the third brake light I see no water trails or water it has rained for two days and the back of my bead liner is soaked right above the rear window truck is a 94 extended cab 4x4 with a slider
Both corners is where it starts the seal on the window looks good and tight

I would seal up the brake light just to be safe. I had the exact same problem and it ended up being the back glass. It looked fine but after i sealed the brake light and it was still doing it i had the window replaced and hasnt leaked since

Thanks I found another thread about it so I'm going to try to caulk the seal first
