2004 Corolla: The blower motor doesnt always turn..heater/AC

Resolved Question:

I have a 2004 Corolla S. The blower motor doesn't always turn on when I turn the heater/AC knob. Sometimes it'll work, but sometimes not. I leave the heater turned on even when it doesn't blow, and if I hit a bump in the road, it'll start working (again, not all the time).

Is this the resistor, or a fuse problem, or what?

If it does this on all fan speed settings then the problem is most likely the blower motor itself and it would need to be replaced, this is typical of an intermittent heater motor not working.
