    All the fuses are good? Inop on all speed settings?
    If the blower has power to it, on all settings, the blower motor may be seized. When you think the blower should be working, try rapping on the motor housing sharply. That should free it temporarily. If it does, replace the motor because it will seize again.

    Capn you are correct, if there is power to the motor and it starts after a sharp blow, it is the brushes worn in the motor. Replace motor for remedy.
