Hi. Generally this concern is caused by the blower motor speed control. It is an electronic device that changes the blower motor speed. That is why resetting the battery will help reset the control module. The control module is built into the blower motor. And is only serviceable with the blower motor. So replacing that should fix your concern. Let me know if you have more questions on that. Thanks.
