Are you saying the blower motor won't work? Check for voltage and ground at the blower motor wiring connector. Give me a second to find wiring diagram.

In the diagram, terminal A is voltage for blower motor, terminal B is ground. If you have good voltage and ground with key on, hvac on, and no blower action, suspect the blower motor.
