Does the A/C work/get cold? If not it could be the blend door motor. If it does, it could be the recirculation door motor.
Curious if you mean when the vehicle is shut off?? If your heater fan continues to run with the ignition key off your blower motor resistor is shorted out.. More then likely.. I've done several on Chevys for that concern.
