Regardless of what I do, the heater does what it wants. I set a low fan speed to blow through the dash vents directly at me, and the "auto" light is not on. But, in about 2 minutes, the blower fan speeds up, the air blows at my feet, and the "auto" light turns on. I want things to stay where I set them, but this car is possessed! It needs an exorcism!
welcome! that is a problem i don't recall reading about before. try disconnecting the 12v negative for an hour, to reset all the computers. is this car new to you?
