Headlight Switch problems of the 2011 Ford Edge

Went to leave at night headlights did not come on and will not come on. Drive to turn just the switch to make them come on did not work either. The low beams nor the high beams will come on.

1. Drivers door ajar light warning stays on. 2. Head lights. The door ajar light and dome light stays on have too repeatedly slam the door for light to go off. Also headlights goes out at night sometime the right light goes out or the left some times 4th they both will go out have to switch the knob back to off position and then turn back on to get the headlights back on.

Driving the blue ridge parkway in nc we entered the first of several tunnels along that route. Headlight switch was in auto-on position as it is always. The headlights did not come on as we entered the tunnel as they do at nightfall. I hit the brakes before either running in to the wall on the right or (worse) crossing over in to the opposite lane. Almost caused a rear end collision as there was a group of harley davidson's behind us. I fumbled with the light switch to turn on, not knowing exactly which way to turn it (as we don't use it since it is in the auto-on position all the time) last time I trust this. We will just turn them on ourselves. Did try to allow the auto-on to work on next two tunnels but it did not. Very dangerous Ford. Why? panic mode, and I'm sure the harley riders were not very happy either.
