1995 Pontiac Grand Am Low beam headlights

Welcome to the forum, sounds like the multifunction switch has a problem. If you want to test wiring circuit, Lite green wire is voltage for high beam, tan wire is voltage for low beam. The voltage circuit to headlamp switch is orange, hot all the time. There may be a multiwire connector under the dash, close to steering column, for circuits going to and from the steering column. You can check the wiring circuits, there. All repair info, say to disarm air-bag, where applicable, when working around steering column.
