Question type: Maintenance & Repair

We have a E350 Ford Box Truck , and our running lights nor our tail lights are working .. We've
checked the fuses and couldn't find one that was bad , so we are thinking it might be the relay. Can
someone please tell me how this can be checked and located?

1 Answer


Your fuses are good. Check for power back at the bulbs sockets. If you have power, check the ground wires for continuity.
