2005 Hummer h2

[Wet hummer]

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?
