What would cause both headlights to stop working at the same time? Bulbs are new and marker lights still come on. All rear lights work just no headlights. Replaced passenger side assembly a month ago

It's relay #46 under the hood. While the lights aren't working but ON, swap relay #43 with #46, your lights will work again. Replace this relay, AND keep a spare in your glovebox. Yeah, it's that common.
