Until very recently whenever I have started the car the heating/AC defaults to the previous settings.
Now, however, when I start the previous settings are not recognised and I have to set up temperature/AC to my previous settings.
I have read the manual, set up the controls and then entered the settings.
Next time I start up, back to previous settings not being recognised.
Am I doing something wrong, or is this indicative of a fault?
All help welcomed
