I sent my car to the dealer to have them do a little work, and it was only when I brought the car home that I noticed a few things had changed. First, the headlights are always on and I have no control over that where I prefer to turn them on when I please. Second, the box that shows the temperature etc. now only shows the miles per gallon. Is there any ways that I can fix this issue myself as I really do not wish to return the vehicle to the dealer for them to keep it for a day to fix this change. Thanks in advance.
