There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.
The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.

I had the same problem. The mechanic could not get the compressor to take in new freon. It has to do with the car's memory. You have to reset it by disconnecting the hot wire from the battery which for thirty seconds. This resets the cars internal memory, so it won't remember that it's out of freon. Reconnect it turn on the car and turn on the air the compressor will start.
