I have an 06 F250 after the recent hurricane wind n rain here at the Jersey shore I developed a leak threw my stock sunglass holder I have no sunroof or anything aftermarket just the stock visor and lighting everything seems tight as far as the naked eye can see just wondering if anyone has seen this or heard of anyone else on hear comment on it would like to trace it before the snow starts up and i lose my headliner. Thanks for any and all help..
Sounds goofy but.. with the truck Nose high.. remove the 3rd Brake Light fixture and check for water. If there is water.. get all of it out and let the void area between the cab roof & headliner dry out REAL good*. (or yul get a musty smell)
What and How this happens ?
There's a channel/lip that runs 360* around the inside edge of the cab roof.. the 3rd brake-light seals are known to dry out and/or.. just leak. When water gets in.. (in your case.. Hurricane driven rain) because these truck set Nose Low.. the water runs around the edge.. to the front.. leaks down through the body seams and trim mounting screws... onto the headliner or overhead trim stuff (sunglasses holder)
The fix is: A new 3rd brake-light gasket.. with a bede of RTV on both sides.. screwed down Snug.. but Not Tight... then tightened a 1/2 turn, in a day or two.
Don't ask me how I learned this.. on my 91 IDI.
