Heres a little something I found out on my H2 that might be a cause in a few of these problems. My H2 was water tight for over a year when I started to notice water dripping off the center console. Upon inspection I found the forward gasket on the center marker light was pushed backwards to the edge of the hole in the roof. I think I found the cause after observing my H2 go through the car wash I use on a weekly basis. Because of the H2's height, the blowers that dry the top of the vehicle are less then 4 inches from the lights. Those gaskets are probably good for normal driving, but the 300 mph(my guess) wind coming off that blower seems to have blasted the gaskets back over the course of a year. So I sealed them up with some RTV, and havent seen a drop since. Its only a theory, but its mine.
