Check Engine & Door Ajar Light Issue
A couple of months ago my check engine light and door ajar lights started coming on together. When you'd open the doors, both would come on. A couple of weeks later, I had a code come up for a loose gas cap. Both lights came on for this as well.
Now, the lights stay on even though I have no codes and the doors are shut. Also, the lights are only on when the headlights are off. When I turn the headlights on, the lights go out. They won't even come on when the door opens with the headlights on.
I've searched the forum and found some mention of this, but I never found a cause or solution. Anyone have any ideas?
