Your blower motor resistor is bad, very very common. It's located behind the glovebox. Remove the plastic kick panel on passenger side and look up. Will be 2 small screws holding it on to the blower motor. Will need to drop glovebox door to get to connector. Best to buy a new pigtail for it also. rockauto will have the pigtail if you can't find them locally.
