Your blower is on fast because a relay that acts as a reostat that lowers the voltage to the blower depending what setting you put it in has blown out. Replace this relay and all will be well again.
The relay in question is usually called a 'Blower Motor Resistor', is usually easy to replace yourself if you can operate a screwdriver, and usually costs between $15 and $50.
