If I am not mistaken, the ECU stores the HVAC settings as they were when the car is shut down. This is to insure that if the heat defrost controls do not properly activate upon startup, you have the most recent settings activated.
I read this in the Bentley Manual...er. I think....gordo
I always shut them off as soon as i start my car, but the next time that i turn my car back on the heaters or A/C comes back on. The dealership said that all their cars do that and they don't know why?? is this true or he just said it cause he didn't know the answer. Does everybodies car do that here???
ahh the climate control defaults to on everytime you start car ie ac/or vent or heat even when you shut it down when driving it will turn on when you start car. thats the way it works you have to live with it sorry
