I have a steady leak from my passenger side B-pillar on my 2013 Unlimited. I think water is coming from the gap between the front a rear plastic rails, soaks the foam behind the rails, and runs behind the rubber corner seal and pours down the door panel onto the floor. (That was kinda long-winded)
I hope this pic might clear up the area I'm rambling on about.
Has anyone else had the same problem?
