You need to have the fan replaced!!! Make sure to get one from Chevy because it is an OEM product... Don't get a rebuilt or replaced from your Schmucks.
The York Air Conditioner that will not come on after it makes a humming sound then stops might have an issue with the electrical current going to the machine. It is possible that the fan is also the culprit. The fan has to come on before the air conditioner can operate properly.
you don't say if it is turning. ??? Replace the starting capacitor.
I don't know about a humming sound but in my 99 GP i have a sort of rattling sound. My mechanic told me that the fan shaft in the "squirrel cage" was bent and that is what is causing the noise. He also told me that it was a pain and faily expensive to fix. I just turn the radio louder. *It could be a loose piece of paper inside the vent pipe or a loose flapper valve between the heat and A/C divider.
Fuel pump?

Some ideas coulb be something is lose and is just rattling or a mechanivcal problem under the hood.
the humming sound is causing the heat? Your fan clutch has failed, or the radiator/condensor have dirt blocking airflow.
i had some type of problem with my Transmission it had a loud humming noise whenever i start, the humming would go away when ever i start moving, but when i came up to a stop sign or a red light the humming would start, my friend who is a very good repair in all type of automotive told me my transmission oil pump was bad, well after he change the transmission oil pump the problem was gone.
Not a continuous source of sound. A vehicle alarm siren is usually is intermittent
