You can give the blower motor a test by applying 12v across the connector. Purple = ( + ) / Black = ( - ). If the blower motor does not respond, it will need to be replaced. If it does respond, suspect the resistor. Both the motor and resistor are accessed from under the passenger's side dash. I've wrapped up the procedures to replace both into a PDF file.
