Replace the PCM fuse located under the hood in the fuse box. Sounds crazy but mine wasn't blown, took it to the dealer and they replaced my "good" fuse with a new one and everything worked again.
It's actually the rubber pad under the master switch. Super odd but this happens a lot on these hummers...I guess the vibration moves it over time.
I had this problem today and thought the solution would be so hard to find that I made a video to help some others with this problem.
