Hello,

There are few reasons for the blower motor to not to come on.
You could have a bad motor, faulty relay, faulty resistor or a wiring issue.
First thing should be checked is the blower motor relay.
Make sure the relay is functional.

Here is how to test the relay:

If the relay is good then the next item to check would be the blower motor.

I have attached the blower motor replacement instructions for your reference. Also included the fuse block diagram, that shows the relay location.

Please let me know of any questions.

Thank you.
