When your dashboard says the fan is on, can you actually hear it running? If not, then the blower motor is bad.
If it comes on and off when you hit bumps and/or hit your dashboard, then you have a bad connection and/or wiring.
You'll have to disassemble the module under the dashboard and check the wiring from the dashboard control all the way to the blower motor itself.
