Thanks guys.
I spent about an hour bent sideways and upside down in my trunk yesterday in the rain with a flashlight.
The driver-side cabin vent is completely dislocated, so I'll get on that right away.
But I also noticed a heavy trickle of water coming down the C-pillar, between the outer body shell and the inner body shell, pooling on the left "ear" behind the wheel well before waterfalling over into the spare tire well.
I'm seriously hoping the rear window seal isn't leaking. I REALLY don't want a dealer extracting the window and trying to reinstall it.
It'll end up worse than it is now.
Maybe I'll try to pin down the leak from the outside using duct tape and a water hose or something and try to seal it myself.
Thanks again.
Isn't Ford great sometimes?!
I can't wait for the car that is both technically outstanding (like the SVT Tour is) AND mechanically sound from Ford.
