Welcome to Just Answer!
Most likely what has happened is the blower resistor has gone bad, very common issue to have happen. You can double check the blower motor by jumping it with a separate power source to be sure it turns. Here:
The blower resistor or transistor is part # XXXXX in this diagram. To access, you will need to remove the glove box for more room to the area. Any other questions, please let me know. Thank you.
Hopefully this went through now.
You will need to remove the lower cover (clipped on), part # XXXXX in this diagram then the glove box, part # XXXXX The glove box is held on by two bolts on the bottom, you need to remove then the glove box will have to be moved a little bit to be removed. The transistor will be screwed on to the blower housing & will have an electrical connector attached to it.
Here is a copy of the circuit for the heater blower motor:
Any other questions, please let me know. Thank you.
