I had a similar problem in a CV, it was the headlight module. You can find a ton of them in the bone yard, I bought one at a pull a part for $5. But I would check switch first and look for any obvious power or wire harness issues.

My problem is solved! Turns out there is a recall on the headlight module, and I'm scheduled to have it fixed at no charge to me.
