never worked on a hummer but rule of the day is that there always is a drain on the firewall on the engine side. usually a small rubber hose about two inches long direced downward. Usually you can stick your finger in there and clear it out. Don't shove anything hard into it or you can punch a hole in the evaporator core.

Yea, hummers are notoriously unreliable. They are gas gusslers too.
I'm assuming this is an automatic?
When the transmissions computer detects any malfunctions, it will give you a check engine light, or something along those lines.
Do the normal checks such as checking the transmission fluid level as per the user manual.
For further diagnostics you'll need to take it to a mechanic. It's impossible to diagnose a problem like this without driving the car and being able to reproduce the problem.

chances are it is your tumbler or parking gear switch. you can replace the tumbler (ignition switch) or the parking gear switch is not recognizing that the vehicle is in park and preventing the key from being turned off
