Hello,
An inoperative blower fan can be due to a bad motor, it can also be for a bar relay or wiring.
The blower motor relay is located under the driver side dash (see picture below)
Check for any corrosion or burnt pin(s).
This relay can also be tested.
Here is a helpful guide:

If the relay is good, using a voltmeter check for power to the blower motor harness. If there is power at the harness, then the motor is likely bad. Be sure to check for any melted connectors at the blower motor.
The blower motor is located under the passenger side dash.
To remove the blower motor first the evaporator case needs to be removed to gain access to the mounting bolts for the blower unit.
The blower unit will come out of the bottom off the passenger side dash.

Please let me know if you have any questions.
Thank you.
