Ok this one has me baffled. I think it's the switch, but then again, who knows. The switch was just replaced about 3 months ago. When I turn on the headlights, the parking lights always come on, but the headlights sometimes take some playing around with. The switch locks in position, but they don't come on. I usually have to play around flashing the brights while the switch is off, then turn it back on. Any ideas? Scott
