Help, my headlights went out

Was driving tonight , turned on the headlights and they didn't come on. I hit the brights and they both came on. Switched off the brights and just my right lowbeam came on. A short time later I shut the vehicle off, when I turned it back on, none of the headlights worked. I hit the bright switch, and the little blue light on the dash came on, but still no headlights. However, now the little blue light stays on no matter how many times I step on the button, and no headlights. My parking lights all work. I unplug the dimmer switch on the floor and the blue light goes out, but still no lights, and the idiot light comes back on when I plug it back in.
The vehicle is a 90 E150 conversion van, with the dimmer switch on the floor. Any help with this would be greatly appreciated.

I would start by replacing the dimmer switch.

If that doesn't work check the headlight switch.

Unplug both headlights and test the connectors for voltage when the switch is on. If the connectors are hot, check for ground. If that's good too, change the bulbs.

If there's no power to the bulbs, you'll have to pull the dash and test the switch and the wires going to the bulbs.

real common in the mid year ford e and f series. take a close look at the light switch. ford did a poor job with the relays till 95, and it takes quite a toll on the headlamp switch.. Kurt

Actually fixed it in the daylight today. Turns out that both the headlight connecters were corroded and once I played with them a little , my headlights worked perfectly....Last night was just too cold to mess with them, and I drove home with a spotlight sitting on the dash shining out my front window. LOL Luckily I didn't have far to drive. Anyone have any easy tricks to cleaning the corrosion off the female connectors?

go to napa and get the electrical conector cleaner. it is in an spray can and makes the job easy. the best way is to remove the pins and clean the connectors individually with a wire brush. there is a release lock you need to push and then the wire and connector will release.. you need a pocket screwdriver or pick to release it. i would check to make sure it is making a good connection and apply a little grease to it to avoid any other future corrosion.. kurt
