Cab leaking upper rear corners , thoughts.

2021 1500 classic , head liner wet back upper corners , no where near 3rd brake light. Thoughts .

There are 2 stripe that run entire top of cab, black, check seals there. Also, check shark fin seal. Would not hurt to get a new seal for the 3rd brake light, just saying, also known weak point.

Not sure if the shark fin is front or rear of cab area on classic, I have a 5th Gen, and mine is at rear of cab center.
