Sad to say it will. I took my truck to the dealership because I just bought it 3 weeks ago and a bulb was out on the 3rd brake light. They had to break the light to get to the bulb because of the seal, then they supposedly replaced the bulb and sealed it back. I took it through a car wash and water started pouring through the corners of my headliner inside the truck. I'm pretty furious to say the least and am expecting the headliner to get replaced or I will throw a bigger fit. 2 days to fix a damn light bulb and now i have water under my headliner.
OK, I'm having the same issue with water coming down my A Pillar after a hard rain. I have a Sun Roof and have been told there was a drain tube connecting the drain hole and out the side/bottom by the door. I have the A Pillar trim removed and do not see any type of tube running down these pillars. Are these tubes in the pillar or somewhere else on the body?
The leak is strange in that it only does it during a hard rain. I can run it through a car wash and nothing. Run a hose over it and nothing. Heavy late afternoon Florida down pour, it leaks.
