depends on whether it's a blower motor or one of the stepper motors. More than likely it's the blower motor as bill said. The blower motor will be your most expensive repair because of the labor involved. If you haven't replaced the final stage resistor then I would take care of that while replacing the blower motor. Labor will probably be 1.5-2hrs depending on the shop and I don't recall the average price of the blower motor.
