posibilities could be that it might not be pluged in the way or the motor is going out.but some times your feet could have kicked the plug loose so look on the passanger side under the glove box and see


It could be a loose plug but its most likely either the, blower motor, blower motor resistor or the climate control unit in the dash itself.
