I think you are looking for the blower resistor which is located on right side under glove box area next to blower motor. these go bad and sometimes burn the harness you can buy a pigtail from dealer if you need new plug

Does it turn off when you turn ignition key off? If so, sounds like your heater/ac control ***'y has a bad on-off switch.

Sounds like a blower motor resistor. Not an expensive part, fairly easy for a mechanic to change. Located usually behind the glove box door.
