Headlight issue

Your right. I think the circuit that enables my headlights to be night or day just went out, both might headlight/high beams work manually of the dash rottary switch. Just have locate the circuit.

Thanks.

Have you checked to make sure the parking brake is not partially engaged?
All it takes is one down click to disable the daytime running lights.
