The running lights turn on, but the headlights will not turn on either in automatic or manual.

There are two different headlight systems for your car so I included both. That being said there are several fuses and relays that work the system. Here are some guides and diagrams (below) that will help us do some simple tests to get the problem fixed.

We must be losing power somewhere.

Please run some tests and get back to us so we can keep helping you.
