Check the wiring harness. In the diagram, the top wires are voltage, hot all the time, Use a voltage tester on the proper color wire. The bottom wires are grounds. On/off, hi/lo beams are controled on the ground circuit. If the ground for low beam has voltage on it, low beam selected, headlamp switch on, there is something wrong with the ground. The wiring itself may have a problem?
