Run 12V directly to the motor and see if it will run, if it dosent than the motor is bad, if it does than the resister is bad, the resister makes the blower run and also regulates the speeds for the blower, but chanses are if it was making a high pitch squeel before it quit the motor went out.

It may be the bearings in the motor are dry or out. You coulod pull the motor and fan assembly out and check its operation while it is out of the heater case. Look for anything inside the heater cavity where the motor sits for any problem hindering motor operation.
