Hey y'all, hoping someone may be able to help me with this.

The tail lights, dash illumination lights and the headlights left on beeper on my 2006 E 250 recently stopped working. All fuses are good.

All input is greatly appreciated.

 

Got rained out at work today so I stopped by the local Ford dealer to talk with my friends there. Guys said that considering all three failed at the same time it is most likely the headlight switch.

So,... picked one up and installed it.

Nope. Not the headlight switch.

Next?

 

Got the multi meter out and checked all the multi function accessory relays. All tested good but one had some corrosion on one of the terminals so replaced that. Still no change.

 

Turned my attention to the trailer wiring connector. Bingo! Connector was shorting out.

Went back to the fuse panel. Yup. 20 amp fuse for "headlight switch" blown.

So... who ever said...

...was wrong!

Yup. I was wrong.

 

My wife loved that part.
