I would suggest checking the blower motor. Give the blower housing under the glove compartment some banging with your fist and retry, if it works, the motor is due for replacement as the carbons have worn off.
If not, unplug the blower motor 2 pin connector and test for battery voltage with ignition switch ON. If voltage is present, ( note wire color or terminal point) plug it back in and use a jumper wire to ground the wire with no battery voltage when connector was disconnected. If blower works, we would need to go into diagnostics with the control panel or power resistor.
If blower motor fails to work, the motor is bad and requires replacement.
