Headlights and door locks not operating?

Hello,

The headlamp relay is located in the fuse block that is under the driver side dash (see picture below). You can test the relay to verify if it is bad.

Did both the door lock and headlight stopped working the same time?
Are you able to unlock any of the door or just the driver side?

I have attached the fuse block diagram for your reference. Also included the diagnostics procedure for the inoperative door locks.

Please let me know of any questions.

Thank you.
