If it doesn't work at all, I'd suspect the motor, they tend to self-destruct as they get old & brittle. If it works on the highest & lowest settings, it's usually the resistor. Either way, some help can be found here;

It's super easy. Disconnect hoses/wires from firewall, remove cover, remove motor/resistor, and as they say "installation is the reverse of removal."
