I NEED TO KNOW WHY MY HEADLIGHTS WON'T TURN OFF

2000 Ford Expedition • 150,000 miles

The headlights on my ford expedition won't turn off. I have to disconnrct the battery in order to turn off. I tried changing the switch on the dashboard but that's not the problem. Someone told me it may be the daylight saving lamps and that the sensor is in the front grill. What should I do?

Inspect and test the DRL relay behind right side of dash
