Re: Water Leak H2 SUT
When this happen to mine, the culprit was clogged sunroof drip lines. Never had a problem with my marker lights.

Re: Water Leak H2 SUT
Well.. i thought the problem was solved until i washed it today.. leak is still there.. i put rtv around all of the marker lights.. I guess next is the drain tubes.. I would think that the sunroof would have some standing water in the drip tray before the tubes if they were clogged.. ???
I dunno.. But I am stumped and the frustration is growing...

Re: Water Leak H2 SUT
My '06 has been in 4 times for roof leaks. Got in it this morning and it was dripping again. All roof lights were replaced, tubes cleaned and the last time, the entire sunroof assembly was replaced. Still leaking. I'm playing the service game while it's under warranty. I've had no fewer than 7 trucks with power roofs and never had a tube clog as the dealers like to claim, but this is the first GM (and probably the last) that I've ever owned. Damn shame that this has been a problem with these trucks since they came out in '03 and they don't have it figured out yet. Good luck.

Re: Water Leak H2 SUT
It took almost 18 months for the Hummer dealer to finally fix the leak on my 2006 SUV. They changed the windshield twice thinking it was that, no sunroof. Turned out to be the roof seam seal over the passenger side. Tried to repair, a sloppy fix, but finally had to replace the seal the whole length of the roof on the passenger side. Just noticed that the seal over the driver's side has some cracks while washing and expect it will start leaking in the future.

Re: Water Leak H2 SUT
Pull the corner roof marker lights there is a rubber plug with the wires running through it make sure it is installed flush and not crimped. Put a little silicone around the edge and reinstall. I also had the issue with the 3 marker lights on the roof as well. Check the onstar antenna as well while you are up there. I periodically use the compresed air for computers and electronics to blow air through the drain hoses. This does not give enough pressure if clogged completly to blow off the drain tubes.
Good Luck, I have been leak free for 5 years.

Re: Water Leak H2 SUT
