It's been dead that long?
Your AC suffers if that fan doesn't work. If you want to test just the fan, since you have to remove it anyway. After you get it out you'll see three wires in it's plug (the plug is behind the fan...). The brown wire is the ground, the blue wire is the high speed feed, the black/blue wire is the normal speed feed wire. Connect the brown wire's pin to a good ground then just touch a 12v source wire to either of the other wires and the fan should come on, either low speed or high speed depending on which wire you choose. If the fan works then the problem could be the two relays ( normal / high ).
Let me know what you find.
