I believe I have a leak at the top of my windshield, since I have a few water leaks on the inside that run down the window, but I can't seem to put my finger on it.
My windshield was replaced several years ago, and I started noticing this right afterwards, though it probably did not experience any rain for some time. I, at least at first, attributed the leak to a faulty caulking job by the installers. I added more of the same 'black windshield caulk' all across the whole of the window, but the same keeps occurring.
Then, I had a thought: what if it's not the windshield, but the marker/running lights mounted right above the windshield, in the top of the front cap?
Sure enough, I got up there, inspected these, and found that all three had 'moisture drops' within the clear housings, a sign of wetness, or at least moisture being allowed into the light housing, and potentially water intrusion thru and below them into the front cap, running down the interior and onto the windshield.
It's so hard to get up front within the coach to see close enough if that's the case, or not, but I suspect it could be. I caulked and sealed these lights as best as possible, yet I still see water running down the inside sometimes - I'm not sure if I made headway in solving the problem, or just caulked something that was not the problem to start with.
I guess I'm just bound to live with it....oh well.
