Q: Leak in window

asked by on September 30, 2016

Hello, my 2011 F-150 is leaking water in the upper back window on the driver side. It will leak even from morning dew (after I start to drive). I've already replaced the 3rd brake light thinking that might be the problem, but still have the problem. I know it could possibly be the window itself, but there is a small black strip over that back corner of the cab. Not sure what's under that strip, but wondering if it could be the problem as well. Is this a common problem? How best can I determine what the actual problem is?
