SOURCE: AC BLOWER FAN STAYS ON
When does it go off (the fan). I assume it does, sooner or later, go off? Some blowers (high-end vehicles) stay on a little longer to clear moisture, but if this just started (hasn't happened since day one) then I would assume it is a short (pray it isn't) or the blower cutoff relay/blower motor relay. If neither relay is available for that car, it could be built-in to the motor. Then, try to unhook the motor and put a tester on the connection plug going into the motor and see if you can get power with the car on, and watch it disappear once the car is turned off, that indicates it is the motor or the resistor atop the motor.

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.

It sounds to me like your compressor got killed. What probably happened is that the airbag got a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag killed the compressor. I would recommend going to strutmasters.com and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. I added the link below so you can check it out.

The power folding function of your exterior mirrors on your '04 H2 depends on a plastic gear to collapse those mirrors at the touch of a button. That plastic gear strips very easily. The service adviser at our Hummer dealership said that problem was rectified in later model years with a redesign of of the collapsing mechanism of those mirrors.
I don't mind manually folding our mirrors, and I was afraid to ask about the cost of the parts required to solve the issue. The service guy didn't volunteer the cost of the fix. Not typically covered by aftermarket extended service/warranty plans.
