Check the rheostat for the blower motor mounted on the bulk head underneath the wipe arms.(this is the most common failure of the fan motor)
I will be a white 4/5 pin connector,
Check that there is supply to one of the terminals using a test light or meter with the ignition turned on.
If there is join this connection to one of the other connections using a piece of wire and the fan will run at full speed proving that the rheostat is defective.
If you have no power to this plug you will need to check the relevant connections and fuse to the motor mounted behind the glove box.

Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.
