At night my headlights do not come on automatically or work by the light switch

Welcome to 2CarPros.

If there is power at the light sockets, then either you have a bad ground or the light sockets are bad. How did you check ground? Did you check the headlamp ground relay?

I attached a pic below showing ground and the relay. Check both. There is a splice in the ground wire, so confirm there is continuity at the sockets.

Let me know what you find.

You have an illumination fuse, should be interior fuse box. Turn on headlamp switch, check fuse, also check fuse circuit for voltage, use a test lite.

The diagram is for instrument illumination.

Check for voltage at the fuse in the diagram, go from there.

A test light is a basic automotive diagnostic tool, doesn't cost much. If your going to work on your own vehicle, you need some of the basic tools.

I can only recommend what to check, you have to do the testing.

Could be a bad switch or relay.
