Under the passenger side of the vehicle, near where your feet are, should be a drain tube. This get clogged from time to time by road grime and usually insects, so carefully use a small screwdriver to clean it out. If this clogs, the A/C system cannot remove its own condensation and it backs up into the car.

Should be on the engine side of the firewall in front of the air conditioner box...usually a small stub hose sticking out...roll it in your fingers and stick a finger into it and generally it will open up.

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.

if you look on the engine side of the firewall you will see a rubber tube on the passenger side of the vehicle bent at a 90 degree angle that is the drain tube. very carefully try to insert something stiff into tube to see if it is blocked
