There is probably something wrong with the fan motor. It could be the fan motor has a bad switch or connection or the fan motor could be bad. The above Answer might be true in some cause's but before I replaced a fan motor I'd check the fuse first. The blower cage could be dirty. I'd bet it's a resistor or a relay. Usually they are right next to the fan somewhere. The wires split off from the the bundle and go to the fan and the resistor.
