I have a 1998 Ford Econline 150. My headlights won't come on. Both are out at the same time. It happened once before, and then they were working fine for a couple of weeks, and today they won't work again. The parking lights work, and I checked all my fuses pertaining to the headamps, (3 in all), and none are fried. I also took the bulbs out of the headlamps, and they don't look like they're bad. Is it possible for it to be the actual switch for the headlights? Any help you can give me at all would be greatly appreciated. Otherwise I'm going to have to try the process of elimination, and that sucks! Thanks, Ed
I would try the dimmer switch. To eliminate wasting money, go buy yourself a test light. You can probe the wires to see if they have voltage.
I haven't worked on a new truck like yours, so I don't know exactly where your dimmer switch is, though it might be down on the column hooked to the lever that you pull. The set-up usually works this way:
You have one wire coming out of the headlamp switch that feeds the voltage to the lamps. But before it gets to the lamps, it goes through the dimmer switch, which decides if the voltage will be sent to the high beams or the low beams. The dimmer switch will usually have three main wires. The wire going in from the headlamp, and two going out, one to the high beam and one to the low. if you don't get any voltage on any of these wires with the headlamp switch on, then I would suspect your headlamp switch itself.
