Hello. Welcome to Just Answer. Please allow me to assist you. the only thing between the headlamp switch and the headlamp relay is the Integration relay located on the fuse panel under the dashboard. When you turn the headlights to ON, the switch sends a Ground circuit to the coil side of the headlamp relay. This allows it to energize and cause the headlamp relay to send power to the headlamps. Pulling back on the lever also causes a ground to be sent, but this bypasses the integration relay. You either have bad headlamp switch or a bad integration relay.
