What you need to do is locate the blower motor. I believe yours is under the dash on the passanger side. There is a power supply to the motor that has a plug where the fan motor plugs in. Disconnect that plug and with a test light or volt meter, turn the fan on and see if there is power to the power supply side of the wiring. If you have a volt meter, you should see different voltages going to the motor based on what speed you set the fan motor to. If you have a test light, it will get brighter the faster you would expect the fan to run. Basically, dim on low, brighter on medium, bright on high. If there is power there, then chances are the motor itself is bad. If there is no power, then you need to trace the wiring back to the resister, relay, switch, power supply (fuse)and so on until you locate where the power stops. Once you locate where the power starts and then stops, you will have located the bad component or break in the wiring.
It sounds difficult, but the worst part is going to be getting to the blower motor itself.
