I noticed that both of my headlights did'nt turn on when I tried them this morning. I' ve got power to the switch and I'm pretty sure relay is good. I tried a known good relay swap. I checked the ground (good) and, at a loss, replaced the switch/dimmer just to see if it was the problem(very expensive). Ohmed wires to terminals (good, both hi/low beam wires). No power to terminals, but It gets power to parking and turn signal lamps and the turn signals work fine. This is an auto switch. 97 JGC.
