I have a 2005 hummer h2. I have been experiencing water leaking in through the garage door opener control pannel. The truck has been back to the dealership 4 times now. The first two times, they allegedly fixed the leak. Now the past two times, they claim they can's find the problem, yet I am still experiencing a water leak. I have spoken to the delaership, and also to the manufactor. Neither one has been helpfull as of now. Basically, they tell me i need to wait for an engineer to look at my truck. Until then, i must carry a rag, and dry all the water, and hope that nothing gets damaged any further. Does any one have any suggestions?

This is not a new problem....search the forum. What I have read indicates that leaks are fixable.

Did you check your roof marker lights seal?

Not that familiar with my hummer yet but my porsche has drains that occasionaly get clogged. Just a thought. Hope you don't have a lemon!

Sounds like marker lights...

the dealer allegedly put silicone around the lights, but they are still leaking. thanks for the input.

wonder if they used the right stuff? Also could be the moonroof drains, or on a slim chance the windshield gasket.

Mine did the exact same thing. One time after a heavy rain the water streamed in, down the dash, and right into the NAV slot. Messed up the screen for a few days until it dried out.

They had a hard time finding the entry point but tracked it to a split seal under one of the marker lights. New light and silicone on them all. No problems since.

I should clarify. The drains are for my sunroof. I imagine the Hummer has a similar set up. Take an air hose and "gentle" blow them out.

After all the complaining, and the after my truck leaking SIX times, GMAC decided to give me a new truck. 2005 SUT, Thanks for all the input

...take it to the carwash and make sure IT doen't leak!

Glad you got things worked out... we had a "lemon" Jeep way back in '89 (before I knew better! ) that we never got resolved! I finally traded in the P.O.S. and never looked back!
