A/C blower is always runing even when the A/C is off

My car has 225000 miles.
My car has an automatic transmission.

Hi There, It sounds like you may have a faulty blower motor relay that is allowing power to the blower motor even when the switch is powered off. The blower motor relay supplies power to this motor when you turn the switch to "on" that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all. This may also cause the blower motor to work intermittently. I would suggest having an expert from YourMechanic come to your location to diagnose your vehicle’s blower motor system.
