    yes it blows air, stay's warm but not cold, don't know about fan or compressor

    The fan will most likely be an electric fan, it is usually at the front of the car, and it is smaller that the main fan for your engine. see if you can find it. Does it run?

    Compressor is usually somewhere at the front where your belt can make contact to run it. You will know if it is running because one pipe will be hot, and the other pipe cold (the pipes I'm referring to are inlet and outlet pipes of the compressor itself.

    Here is a picture of a compressor, yours may vary in some ways, but this is just a general idea for what you are looking for

    could you please give more details?
    Does it blow air at all?
    Warm or cold air?
    Does it stay that way or does it change?
    Does the fan run? How about the compressor?

    Details, details and more details :-)

Another way to know if your Compressor is running is you will see the pulleys rotating, when its off the fan just runs along it until turned on a clutch will engage and the pulley will begin turning the compressor. You will also hear in run, it may or may not shut off and then run again for a few seconds, then off (it depends on the AC System) - Some run all the time, some cycle on and off

here is another picture to help you understand what i mean

2004 chevy blazer ac stoped working and if the ac is turned on it stoped the engine abruptly, the pressure on the low pressure port without the engine on reads high at 150psi which is the red danger zone...

I would suspect you have a bad A/C compressor. When you engage the A/C, the clutch locks up the pulley which kills your motor from the drag on the belt. Replace the compressor, evaporator and valve, then recharge system to 55 psi.
