Blower motor some times does not shut off, even if turned off by key, has drained battery in past, sometimes it does, but I unplug at blower motor to be safe, I've been told it mite be the heater core blower motor resistor, where I unplug it, any input?, I'm not able to pay for I have been operated on 1 1/2 years ago and have little use of right arm And not much I can do right now, they say it will come around but I'm about out of dough, Thanks for understanding.

I don't believe so, just ac/heat control in dash.

So, it DOESN'T have an auto setting where you just select a temp, right?

That would mean that you likely have a bad blower motor resister located next to the blower motor.

No I don't have a way to select temp, resistor I've been told about, this would work sometimes and not other's, when it stays on its on high and can't be shut off, then all of a sudden it will work normal on any speed and also shut off correctly?

Now that I look at this I have a dial that turns ac/heat on and off it can be on the red for heat and then can be turned to the blue ac, it will control how hot to cool you can make things, u can go strong or light to the heat or strong r light to the ac, , would that be considered an auto control? Thanks
