Check the fuse. There may also be a relay for the blower.

Yes on both Tony - If the blower motor was also replaced then it's possible that the speed selector switch is burned (not uncommon). The resistor will only keep the fan from blowing on speeds other than High Speed. Often, the fan gets old, the resistor pack blows it's protective fuse, the driver uses the only speed left - high speed - and the worn out motor draws a lot of amperage through the switch and burns it out.
