If your blower went out, the air conditioner would not be blowing. Are you trying to say compressor went out, and a/c is blowing warm? If that is the case, you might have a leak that is causing prevention of compressor operation. You can hear, or observe the compressor by first cycling the switch on and off listening for the snap of the clutch, and change in rpm. Also, with the engine running, and A/C on, follow the belt down the front of the engine below the generator to the compressor, and see if the front drive plate is engaged and spinning, or stationary. It may require a flashlight to see it, it is the lowest belt driven accessory, on the front of the engine.
