The blower motor resistor plug should be on the center part of the HVAC unit if I recall correctly, it'll be a 4-pin plug. If the fan comes on when you turn the blower switch to max then you don't have the resistor plugged in.

If it doesn't come on at all then most likely it's the blower motor relay or a fuse.
