Simply remove the colored lenses on the lights above the windshield. You then remove two screws that hold the housing to the cap above the windshield. You can then caulk or use the window tape to reseal the back of the housing and screw the housing back in place. Pop the colored caps back on and there you go.

Yes window was the same. Issues with the windshield as well. Replaced rubber seal that runs along the top of the windshield/water was still getting in. Placed bead of caulking along the top portion of the rubber. Have yet to use hose to make sure no more leaks. My brother has a 2002 Adventurer with same issue. Turned out it was the lights along the front cap above the windshield. Check those as well. You need to remove the entire housing and seal behing the portion of the fixture that attaches to the rv. Don't just seal the colored cap, it won't resolve the problem. Winnebago has had some issues with windshields leaking. I also read that one person used the same tape I used to replace the driver window on the rubber seal above the windshield and that seamed to work very well. Good luck
