Hit the blower motor with a hammer handle and see if it starts, if it does replace the blower motor, if it doesn't replace the blower motor resistor located next to the blower motor in the air ducting with the connector sticking out of the air ducting

Quite possible a blown fuse. However there is also a blower control module located under the hood near the center of the fire wall. It bolts into the heater box assembly, not to far from the blower motor. You may have to remove the relay/fuse cover assembly to see it. They are known to short out and cause all kinds of problems. Remember though it could also be a simple fuse in that area or under the dash. The worst case here is the whole climate control system in the dash failed.

For most common location, open hood and look near cowl for a plug near the air conditioning box just forward of the windshield wipers. It should have several wipers and the resistor itself protrudes downward into the box held in place with two screws. Screws have 7mm, 8mm, or 1/4 inch hex head.

If not: look near blower itself under the dash on the passenger side. The resistor should protrude upwards into the HVAC housing near the blower.
