There are a few possibilities;
The light sensor has failed
The Auto Lamp control unit failed
The Autolamp Relay has failed
The headlight switch, right side controlwith headlight switch, AUTO position is not making a continuous circuit and not providing 12Volts to the Auto Lamp circuit
Below and in the next post window I have provided the wiring diagram for the Auto Lamp circuit and the location diagram of the dash showing relay and control unit locations
