It depends on how old the furnace is. If the furnace is really old (20-25+ years old), you may have a mechanical relay for the blower. If the furnace is newer, it likely has a circuit board controlling the furnace and blower.
Do the burners light on cue?
Can you provide a picture of the furnace (covers removed)?
