A cap is usually strapped to one side of the blower assembly.
Be careful as they will hold a charge for a few minutes after removing power. If the motor will spin freely with power removed replace your cap. match voltage and microfarad.
this is a 5mfd 370 volt example...
"Tip of the Day" Remember to remove power first.
