My defroster, heater and air conditioner will work; however, the fan will not blow.

If your ac blower is not pushing air then it can be one of two likely causes. If the fuse for this circuit is good, and no air is coming out when any fan speed is chosen then you have a failed blower motor. If the fan only doesn't work on certain speeds but will work on at least one speed, then you have a failed blower motor regulator.
