What would cause the blower motor to keep blowing after shutdown. It drains the battery from slightly blowing all night

It is inside the vehicle. I didn't even realize it for a few days that it blows because it is so slight but that is what is draining the battery. It takes all night and dead in the morning. I will gladely make the donation if you think you can help

Its lower then the lowest setting you can put the blower motor on? Or is it the same speed as the lowest setting?

If that is the case I would be checking the blower motor control processor or the relay.

The processor is located under the right side of dash near the blower motor.
