AnswerIt is an Electric Blower, And it senses that the vehicle is still very warm, so it keeps running to cool the engine -Mr. Mechanic-Could also be the blower motor resistor if it wont turn off at all
If it's a fan speed issue check the blower motor resistor & the blower motor. Check the plugs at the resistor and blower motor for burn marks also.
Could be,Blown fuse,Bad blower motor,Bad blower motor switch,Bad blower motor speed resistor,
where is resistor pack on 2010 impala lt 6 cylinder 3.5 motor
