What is your question?
I had DRL but no headlights when I turn on the switch. Could they both burn out at once?

Vehicle Application: 1999 Toyota Corolla 1.8L, Vin R Customer Concern: Daytime running lights work. Headlights inoperative. Relays buzz. Tests/Procedures: Check the controller for burnt spots. Verify the current draw for all the relays. Look for a burnt connection to the ground supply to the controller. Potential Causes: Defective Connector — Bad connection to ground for controller main ground. Lamp Control Module Relay
