Many cars have a separate high blower relay to control the extra amperage draw, or control blower speed through a series of resistor coils. Failure in either one might cause you to have lower speed blowers, but not maximum.
If you have no blower at all now, check for power at the blower motor. This can be done with a simple test light ($5 or $6 at any auto or hardware store). Power there = bad blower motor. No power? Repeat the test at the switch. No power through switch = bad switch. Power through switch? Locate the relay. It's probably your problem. You have just saved yourself $60 - $100.
