Heat not blowing from heater. Fan switch not working properly

My car has 1278090 miles.
My car has an automatic transmission.

Hi there. The blower fan switch not working may be, a blown blower motor fuse, a faulty blower motor relay, a faulty blower resistor, a faulty blower motor, and/or a faulty blower motor switch. Proper diagnoses should be performed to avoid unnecessary repairs. The inoperative heater should be diagnosed, once blower operation is restored. I recommend having your vehicle’s heater is not working be diagnosed and repaired by a certified technician, such as one from YourMechanic.
