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.

looked it up online and looks like it's on the front of the water pump in a thing called the coolant inlet housing. one end of it looks something like the letter y and the other end, where the thermostat is round. hope that helps

you should check the fuse in the fuse boxe under the hood and find the radiator fan fuse
if the fuse is no longer good the little piece of metal will be cut in the middle so replace it with the same number if it's a 20 AMP do not put a 30 or a 15 AMP
if the fuse is good then there might be some problem with wires (could be cut) or the radiator fan motor is no longer good
you should have it check

Check the hazard switch brother. Thats a know source for this problem. Mess around a bit with it for a temporary fix but replace it at any rate!
