Default 2003 Hummer H2 sunroof leak!

Anyone have any pointers on sealing up a sunroof?

I assumed it was marker lights and siliconed them. But after a normal rain I still get tons of water pouring down on me when I go to drive away.

It drips down from left and right handles and around headliner around sunroof.

Do I need to remove the whole headliner to seal up? Or worse the sunroof?

The drains are most likely plugged. You need to get up there and try pouring some water down them and see if the water evacuates. If not you will either have to find something you can push through to get the debris out or use an air compressor.

DRAINS? Where are those? Can you snap a photo?

OK, went to open the sunroof to inspect the drains and found the sunroof has no power to open. I press the button and nothing. I would never open it anyways so is there a way to open manually?
