Winshield Leaking

As the title says, I discovered today after washing my car, that the windshield is leaking. I installed new carpet a few weeks ago, so I wasn't too happy. The leak appears to be coming from the drivers side, just above the lower right corner of the windshield (vertical part). I'll provide some pic's of the area in question tomorrow.

I do know the weatherstripping and glass were replaced a little over 10 years ago. The weatherstripping is in excellent shape, since for most of the past decade, the car has been garaged. The previous owner was unable to get the chrome trim installed on the bottom, passenger and driver's sides. The chrome trim just won't stay on the clips. There appears to be a lot of sealant used around the weather-stripping (black goop), which is probably why the clips aren't snapping correctly onto the trim. Just wondering what I could use to seal the existing leak for now. Furthermore, some parts of the weatherstripping are higher than other areas, i.e. the trim clips are easier to get to in the lower areas. Could I shave the rubber on the weatherstripping to even out the plane? This way, the trim may be able to clip correctly and stay put. Anyone else have issues with those clips not holding the trim in place? Thanks

Edit: Yes, I spelled windshield wrong in the title....
