The switch is a four position switch. The way that the blower is functioning, there is no off unless the ignition key is fully turned to the left so that there is no current flowing. The blower has been acting like that since we bought the car three years ago so if the first position of the switch is actually supposed to be an "off", it is not working like that. The other positions (2, 3, 4) work as I said (medium, medium, low). I would expect position four to be high. If you are saying that position one should be "off", there certainly is a problem somewhere. However, it is not the blower switch or the blower resistor as I changed them both out - and the problem still continues.
